Tribological characterisation in dry sliding conditions of compocasted hybrid A356/SiCp/Grp composites with graphite macroparticles
(Springer London Ltd, London, 2019)
The influence of SiC microparticles reinforcement and graphite macroparticles addition on the friction and wear characteristics of A356 Al-Si alloys, produced by compocasting, has been assessed using a pin-on-disc tribometer. ...
Design aspects of light aircraft wing spar—Differential and integral approach
(John Wiley and Sons Inc, 2019)
Three different wing spar designs (differential, equivalent integral, and optimized integral) are analysed, in order to establish the optimum one. Numerical analysis was carried out by extended finite element method (XFEM) ...
Parametric optimization of the aluminium nanocomposites wear rate
(Springer Heidelberg, Heidelberg, 2019)
The optimization of wear rate of the nanocomposites with A356 aluminium alloy matrix, reinforced with silicon carbide nanoparticles, was performed through the analysis of the following influences: wt% of the reinforcement, ...
Butt welded joints assessment after fire exposure
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
The need of in service life of a steel structure after being exposed to fire raises the problem of strengthening or replacement of some structural elements. In many cases, after structural safety assessment, fire exposed ...
Efficiency and power upgrade at the aged lignite-fired power plant by flue gas waste heat utilization: High pressure versus low pressure economizer installation
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
A substantial potential exists for the recovery of flue gas waste heat at aged coal-fired power plants. High and low pressure economizers (HPE, LPE) can be applied for this purpose. Two cases of the feedwater supply to the ...
Multidisciplinary research method for designing and selection of bio-inspired profiles in the conceptual designing stage
(Springer Heidelberg, Heidelberg, 2021)
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 ...
Radionuclide Immobilization by Sorption onto Waste Concrete and Bricks-Experimental Design Methodology
(Springer International Publishing Ag, Cham, 2019)
The utilization of construction and demolition waste materials for the radionuclide immobilization by sorption processes was investigated. Given that the liquid radioactive waste usually has a complex composition and that ...
The Effect of Vanadium Content on Microstructure and Impact Toughness of Forged High Alloy Steel X96CrMo12-1
(Springer International Publishing Ag, Cham, 2019)
The aim of this research was to examine the influence of vanadium on the structure and impact toughness of the forged high alloy steel X96CrMo12-1. It is known that vanadium affects the process of solidification of this ...
Possibilities for wider investment in solar energy implementation
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
Installing of new solar capacities for electricity production has slowed down worldwide. To explore this trend, to assess opportunities for implementing solar potential, and to determine whether wider investment in solar ...
Upgrade of the thermal power plant flexibility by the steam accumulator
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
Thermal power plants are forced to operate under frequent load changes in energy systems with increased share of solar and wind power plants. These load changes increase thermal power plant aging and reduce their efficiency. ...
