Scientific FabLab at the Faculty of Mechanical Engineering University of Belgrade - Support for Experimental Fluid Flow Research
Apstrakt
Complex fluid flow phenomena, as well as energy and cavitation characteristics of hydraulic machinery and
equipment are studied in the Laboratory for Hydraulic Machinery and Energy Systems, Faculty of Mechanical
Engineering (FME), University of Belgrade (UB). Research in the Laboratory comprises micro to macro scales
fluid flow research. In Laboratory exist installation for investigation of the energy and cavitation characteristics
of turbine models (Francis, Kaplan, bulb), installation for research and visualization of the cavitation in pumps
and on the hydroprofiles, installation for pump testing, educational-demonstrational set-up for testing hydraulic
pump and Venturi flow meter calibration, installation for testing valves, four installations for volume flow
calibrations: up to 10 l/min, 3 l/s, 50 l/s and 200 l/s, three installations for turbulent swirl flow investigations in
air behind the axial fan impeller: in pipe, diffuser and jet, open wind tunnels for calibra...tion of velocimetry
probes: up to 10 m/s, 36 m/s and 60 m/s, and etc. In this lecture will be presented new results obtained in
Laboratory, from idea, computer modelling and numerical simulation to realization of the experiments.
In Laboratory exist various measuring and calibration devices, as well as machining systems. Novel
measurement systems would be presented: three-components LDV (laser Doppler velocimetry) system, stereo
particle image velocimetry (SPIV), high speed SPIV, micro PIV, calibration of pressure devices with air and oil,
and etc. Some results of laser based turbulent swirl flow research are presented. Complex experiments seek
thorough preparations, so production capacities must occur in such a big laboratory. This is organized in the
Laboratory workshop. CAD (the computer-aided design) 3D models are designed in various softwares. Two
CNC (computer numerical controlled) machines are fully operational: 3+1-axis vertical machining centre (1016
x 508 x 635 mm), 5-axis vertical machining centre (1270 x 660 x 635 mm). In Laboratory many other machines
exist, like vertical drilling machine, another milling machine, one lathe machine, and etc. Other complex
machines exist in the Department for Production Engineering at FME UB. In addition, Printrbot Simple Metal
3D printer is also applied in the Laboratory. For collaboration with students, researchers and sophisticated
industry, these capacities are organized in Scientific FabLab [1, 2].
Realization of ideas is encouraged in the Scientific FabLab. In fact, 3D model and production simulation
software reveal all important points in ideas realizations. Student project - axial compressor blade could be
printed and they can study geometry in vivo, not only by computer 3D model [3]. They can also print designed
centrifugal pump impeller [4]. Production on CNC 3-axis machine of radial centrifugal impeller in duraluminiun
is presented in lecture, as well as designed mould for axial impeller blade [5]. Additional aspects of production
of laboratory educational model and its integration in remote laboratory are also presented here [6]. In
Laboratory is established procedure for repairing hot-wire anemometer (HWA) probes, with help of Prof. Dr
Petar Vukoslavčević, University of Montenegro, Faculty of Mechanical Engineering. It is used for positioning
and welding small sensors (2.5 microns or even lower in diameter) on the HWA probes prongs using stereo
microscope and the original micro positioning device with fifteen degrees of freedom [7]. These HWA probes
are afterwards used for turbulence measurements. In Laboratory are applied, as well as developed, novel
measurement techniques. Technique and procedure for affordable and "do-it-yourself" PIV measurements are
developed in Laboratory [8]. This technique is planned to be used for fluid flow research in micro channels [9].
Recent investigations are focused on micro channel manufacturing and some results will be presented [10-11].
In addition, acquired experience in knowledge dissemination through open access workshops will be introduced.
