AB  - Biomimicry as a scientific-research field, with a specific approach to the creation of useful value, methods, and systems based on the understanding of Nature, aims to improve the quality of life, preserve Nature and live in harmony with Nature. The most famous example of biomimicry of the shape of a kingfisher's beak on industrial design is the bionic high-speed train (BHST) of the Japanese railway - the Shinkansen. In the literature, for about thirty years since its creation, no description of the method of performing biomimicry has been found, one that resulted in the exceptional characteristics of BHST: reduction of noise, an increase of speed, reduction of consumed energy, and cost price. The presented biomimicry method for high-speed train aerodynamic design (BMAD) aims to offer a way to perform bird-to-train biomimicry. BMAD contains phases: acquisition of new knowledge and skills from different fields; selection and examination of biological samples; investigation of kingfisher biomechanics in diving maneuver; research of bionic 2D BHST; biomimicry of diving maneuvers - a combined method for determining the similarity of 2D flows bird - BHST; BHST 3D concept-design research and BMAD validity assessment. BMAD applies various numerical and experimental methods, some of which were developed based on biomimicry: aerodynamics (flying animals), hydrodynamics (swimming and diving animals), part of fluid mechanics and computational fluid mechanics (flying and swimming, noise, turbulence, etc. ), thermography (snake vision), rigid body mechanics (biomechanics) and 3D laser scanning (bat echolocation). BMAD, despite limited sources and resources, represents a collection of new knowledge and skills, which gave realistic results and opened up a completely new possibility of optimizing the method and design of BHST. In the design process, BMAD is compatible with known design and optimization methods. By improving BMAD, research results would become more quickly available, more precise, and more reproducible.

AB  - The corrosion behavior of AA7049 aluminum alloy in NaCl solution in the presence of environmentally-friendly corrosion inhibitors (Ce-chloride, Ce-formate, Ce-acetate, and Ce-propionate) was analyzed. The chemical composition of intermetallic particles was evaluated by a Scanning Electron Microscope, equipped for Energy Dispersive Spectroscopy measurements, while the presence of cerium and type of functional groups in inhibitors surface layers were analyzed by X-ray Photoelectron Spectroscopy and Fourier-Transform Infrared Spectroscopy, respectively. Inhibitor efficiencies were tested by applying electrochemical techniques such as Electrochemical Impedance Spectroscopy and Linear Sweep Voltammetry. Ce-propionate showed a greater inhibitory effect than all other tested corrosion inhibitors. The inhibitory effect decreases in the following order: Ce-propionate > Ce-acetate > Ce-formate > Ce-chloride. Propionate anions have a higher water contact angle and also a longer aliphatic side chain than acetate and formate anions. The mechanism of inhibitory action of Ce-propionate and other tested corrosion inhibitors has been proposed.

AB  - A multidisciplinary research method was employed with the intention to create a series of bio-inspired flattened airfoils, observe their aerodynamic characteristics, and analyse their applicability to small devices or to designs of high-speed trains, within the shortest period in the conceptual stage. A research specimen of a kingfisher, selected for biomimicry, was examined with the following methods: visual inspection, analysis of photographs, manufacturing quality control measurement with a 3D laser scanner, and microscopy. A basic multi-arc-line profile, re-engineered from the overlapped specimen shape data and based on the observations, was used for designing a series of seven derived airfoils. The aerodynamic characteristics of the bio-inspired airfoils were obtained with the panel methods at low and moderate subsonic speeds, while the small transonic difference method was used in the high-subsonic speed range. Basic and ellipse-like airfoils produce higher total drag at low and moderate velocities and higher forebody drag in the high-subsonic range when compared to derived and parabola-like airfoils. The obtained critical Mach numbers are in the range from 0.76 to 0.78, where three bionic airfoils show values equal to or smaller than the values of ellipse- and parabola-like airfoils. The profile with the shortest bio-inspired relative chord has a higher critical Mach number value than the parabola-like profile. The sonic lines above these profiles appear at close positions. The applied set of examination methods of the bio-inspired design is not time consuming and produces sufficiently good results in the conceptual stage. Therefore, a further development of unique and adjusted numerical methods and codes at pre-computational fluid dynamics run is encouraged, together with shape parameterization.

AB  - In the times of significant development of high-speed train transportation and taking the primacy over the others, one of the major designing tasks is to predict accurately and fast the vehicle’s main performances, especially aerodynamics. Motivated by the bionic design of representative Japan’s train Shinkansen, the presented bionic design was based on the observations of the kingfisher from Serbian national heritage collection. The specimen beak shape has been measured, by laser scanning, and converted to a mesh. Afterward, the longitudinal cross-section of the beak was implemented to a bionic high-speed train design. As the critical, the conditions of the train’s forehead entering into the tunnel were selected, while the case scheme employed relative motion. The forehead contour distributions of the surface temperature, skin friction coefficient, and the pressure distributions, obtained with computational fluid dynamics, were used for the prediction of the transition zone extension. The anomalies in surface temperature behavior were additionally analyzed by pressure and density distribution inside the tunnel and over the forehead. Besides the gross time history of the pressure derivative of time is in correspondence with the referent, it was interpreted that the true biological form is not fully suitable for adoption for bionic design. The development of this design, employing contour simplification by the close parabolic function will continue in the future. This work suggests an economic and efficient approach to analyze the results of the Reynolds-Averaged Navier-Stokes equations adequate for the concept design stage.

AB  - This paper presents a study of a free convection flow around the walls of a ventilation mill of the Thermal Power Plant "Kostolac B", Kostolac, Serbia. A combined method consists of thermography and software post-processing, PATS. The PATS is specially developed for recognition of turbulence zones by the custom processing of large input data sets from thermal videos. The calculations determine maximum temperature fluctuation i.e. peak-to-peak fluctuation at every spot during the recording time. Three thermal videos of the walls were analyzed. Maximum temperature fluctuation occurred in the zones close to the obstacles, which are thus recognized as one of the main sources of turbulence. Besides, PATS has recognized fine camera oscillations and mechanical movements of a flexible material near the dozer wall. The detected zones of turbulence correspond to the previous studies and to the theory. The method shows good potential in the field of free convective flow research through the improvement of testing efficiency and cost savings. State-of-the-art thermograph cameras and updated software are recommended.

AB  - The paper analyses the corrosion behaviour of naturally and artificially aged AA2024 alloy in NaCl solution and in the presence of an environment-friendly corrosion inhibitor, CeCl3. On the basis of the values of polarisation resistance and corrosion current density, the corrosion resistance of the protective inhibitor film is established as well as the general corrosion resistance of this aluminium alloy. Resistance to pit formation is determined based on the difference in pitting and corrosion potentials while resistance to pit growth is determined based on the amount of charge consumed during pit growth. A scanning electron microscope is used to examine the morphology of the pits formed during the pitting corrosion testing, as well as to determine the cerium content on intermetallic particles and the matrix AA2024 alloy. The corrosion behaviour of AA2024 alloy is investigated after different test periods in NaCl solution and in the same solution with the CeCl3 inhibitor. The corrosion resistance of both tempers of AA2024 alloy is more than one order of magnitude higher in the presence of CeCl3. An explanation of the observed differences in the corrosion behaviour of the naturally and artificially aged AA2024 alloy is proposed. Different corrosion behaviour of the alloy after different test periods is also explained.

Korišćen je Nd:YAG laser, energije do 750mJ i talasne dužine λ=1064nm i 532nm. Efikasnost čišćenja je ispitivana u funkciji energije lasera, talasne dužine, broja impulsa, odnosno vremena eksponiranja i vlažnosti površine uzorka. Rezultati skidanja nepoželjnih slojeva sa površine uzorka, kao i morfoloških promena na osnovnom materijalu, ispitivani su optičkom i skenirajućom elektronskom mikroskopijom ( OM i SEM), a ispitivanje mikrohemijskih promena izvršeno je pomoću energijske disperzione spektrometrijske analize (EDX) i rendgensko fluorescentnom spektroskopijom (XRF). Pokazano je da za čišćenje ovog uzorka veću efikasnost ima λ= 532nm i da je uticaj vlažnosti površine na efikasnost laserskog čišćenja veoma mali. Istraživanja obavljena na arheološkom uzorku iz Dunava, pokazuju da je primena lasera u čišćenju nepoželjnih slojeva veoma efikasna, bezbedna i ekološki prihvatljiva.
AB  - The paper presents the results of laser cleaning of corrosive and other deposits on a metal archaeological artefact from the Danube. Nd: YAG laser, energy up to 750 mJ and wavelengths λ = 1064 nm and 532 nm is used. The cleaning efficiency was examined in the function of laser energy, wavelength, and number of pulses, i.e. the time of exposure and moist of the surface of the sample. The results of removal of unwanted layers from the surface of the artefact and morphological changes on the base material were examined by optical and scanning electronic microscopy (OM and SEM). Micro-chemical changes have been determined by energy dispersive X-ray analysis (EDX) and x-ray fluorescence spectrometry (XRF). It has been shown that λ = 532 nm has higher efficiency for cleaning this sample and that the surface moisture has very small influence on laser cleaning efficiency. Research carried out on the archaeological object from the Danube shows that the application of lasers in the cleaning of undesirable layers is very efficient, safe and environmentally friendly.

AB  - Methods of diagnosing aerodynamic characteristics are constantly developing in order to conduct the precise and energy efficient wind tunnel testing of transport vehicles in the prototype design early stages. This is of a special importance when facing the time/cost consumption problems of detection of the transition zone over the simplified design of the high-speed train. Herein the applied thermodynamics found a very significant role in the field of experimental aerodynamics. With the intention of detecting the boundary-layer transition zone the following measurements were applied: the infrared thermography, flow visualization, and drag force measurements. In addition, the CFD was applied to predict the flow behaviour and transition zone, solving PDE consisting of the Reynolds-averaged Navier-Stokes equations, energy equation, and the equation of state for an ideal gas employing density-based solver. The thermal imaging defined the transition zone by simple application, and fast recognition, while the transition bounds were defined in the analysis. The flow visualization confirmed thermography results and the method itself as favourable, especially in the most expensive early phases of redesigning for aerodynamically optimized and energy efficient solutions. The numerical method was confirmed by the experiments, resulting in acceptable differences in the definition of the transition zone. For a better understanding of the phenomenon, the overlapped implementation of the presented methods focused on forced convection showed as the best solution. Based on the experiences of this research, development of the additional equipment and adjustments will be introduced in the future experiments.

AB  - Wind tunnels are the aerodynamic laboratories which task is to enable high quality  and stabile airflow in controlled volume, a test section, during run time, in order to study the effects of streaming around various aeronautical or nonaeronautical models (airfoils and bluff bodies with complex motorized or robotic constructions). The main requirement that leads to quality and reliable measurement results is a high flow quality in the test section: uniformity of the velocity and pressure fields along and across the test section, low turbulence level and low flow direction angularities or swirling. The knowledge of low parameters enables the exchange of the scientific and technical information, comparison of the experimental results from different wind tunnels and data scaling of the model to the real scale.

abstract = "Wind tunnels are the aerodynamic laboratories which task is to enable high quality  and stabile airflow in controlled volume, a test section, during run time, in order to study the effects of streaming around various aeronautical or nonaeronautical models (airfoils and bluff bodies with complex motorized or robotic constructions). The main requirement that leads to quality and reliable measurement results is a high flow quality in the test section: uniformity of the velocity and pressure fields along and across the test section, low turbulence level and low flow direction angularities or swirling. The knowledge of low parameters enables the exchange of the scientific and technical information, comparison of the experimental results from different wind tunnels and data scaling of the model to the real scale.

AB  - This article presents results of a numerical and experimental study of the temperature distribution inside and on the walls of the ventilation mill in the Kostolac B power plant, Serbia. This is very important because heat exchange between gas mixtures, ventilation mill walls and the environment, influences coal powder temperature, the combustion process, and the emission of greenhouse gases. The most complex multi-phase model in the Euler-Euler approach has been used through the ANSYS FLUENT code, for the numerical simulation of temperature distribution. Two ventilation mill models have been considered, one with zero wall thickness and the other one with steel walls, with and without insulation. An infrared thermographic camera was used for monitoring the temperature distribution on the outside wall of the ventilation mill housing, before insulator reparation, while after the reparation measurements were carried out at the selected points with infrared thermometer. The experimental results were used for verifying the results of the numerical simulation method as well as for detecting the damaged insulation.

AB  - Numerical simulation of 3D multiphase flow is performed to determine the velocity field in the fan mill. The mixture model of the Euler-Euler approach is used. Recirculating gas is a primary phase that carries granular phases including the coal powder and sand. The latter causes heavy wear of mill impact plates. The optimal form of hardfacing geometry and technology has an impact both on velocity magnitude and direction of flow in such a way as to reduce plate wear. This paper presents results of surface modification (based on numerical simulation), implemented on impact plates of the fan mill in the Kostolac B power plant in Serbia. Fishbone hardfacing is made in order to increase the lifetime of impact plates and extend the period between overhauls of fan mills. The experimental tests of fishbone surfacing plates, in exploitation conditions, show that the applied modification, hardfacing technologies and coating materials, give expected results. The application of this hardfacing in the form of a fishbone is simpler, faster and more economical compared to complete overlaying and honeycomb impact plate surfacing. The relative weight loss of base plate after an 1440-hour period of exploitation is 8%, while the weight losses for the hard-faced plate is below 7%.

Voz se sastoji od dve lokomotive, na svakom kraju, i četiri putnička vagona., ukupne dužine 121m. Aerodinamičke kočnice stvaraju silu kočenja povećavanjem aerodinamičkog otpora pomoću izvučenih panela na krovu voza. Simulacije strujanja su urađene softverom Fluent 12.1, za voz bez, sa jednom, dve i tri aerodinamičke kočnice, pri brzinama od 30, 50 i 70m/s. Sila otpora po jedinici površine panela je određena kao funkcija brzine voza i položaja aerodinamičke kočnice. Doprinosi ukupnoj sili kočenja svake od kočnica, određeni simulacijama su: za prvu 24%, za drugu 15% i za treću 14.8% i pokazali su , zajedno sa raspodelama pritisaka po panelima, dobro slaganje sa proračunima aerodinamičkog otpora za ravnu ploču upravno postavljenu prema strujanju.
AB  - This work presents the research results of the aerodynamic brake influence, mounted on the high-speed train's roof, on the flow field and overall braking force. The train consists of two locomotives at each end and four passenger cars between, with 121m of overall length. Aerodynamic brakes are designed to generate braking force by means of increasing the aerodynamic drag by opened panels over the train. Flow simulations were made by Fluent 12.1 software, for the train without and with one, two and three aerodynamic brakes, and velocities of 30, 50 and 70m/s. Drag force per unit panel area was determined as a function of train's velocity and the brake position. Contributions to train's gross braking force of each brake, obtained by simulations were: for first 24%, for second 15% and third 14.8%, and showed, also with panels' pressure distribution, good correlation with the aerodynamic drag calculations for flat plate orthogonally disposed to flow stream.

AB  - This paper presents the results of simulations, carried out with the Fluent software, for a high speed train moving at 70 m/s for 4 cases: the train configuration without aerodynamic brakes, the train configuration with one aerodynamic brake, with two, and with three aerodynamic brakes deployed over the roof of the train. We have determined the braking force per unit area of aerodynamic brakes and compared our results to the results found in literature. Since it is known that the brake panel installed in the first position creates the greatest resistance, while for the brakes in the second and subsequent positions the intensity of resistance decreases, we analyzed the effect of serial interference and determined the contribution of each brake individually to the total braking force, depending on its position.
