Study and analysis of the cavitating and non-cavitating jets part one parameters controlling force, power, and the jet behavior
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2020)
This paper presents the dependency of the jet power and the cavitation intensity on the working conditions of the cavitating and non-cavitating jet flow. This dependency is indicated by the cavitation erosion process and ...
Entropy and fractal nature
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2020)
Existing, the biunivocal correspondents between the fractal nature and the nature discovered by fractals is the source and meeting point from those two aspects which are similar to the thermodynamically philosophical point ...
Study and analysis of the cavitating and non-cavitating jets part two parameters controlling the jet action and a new formula for cavitation number calculation
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2020)
This part of the paper presents the relation between the working conditions, nozzle geometry, nozzle diameter, and jet behavior. Experimental work has been made by impinging the submerged jets on the copper specimen as a ...
Continuous slow dynamic slope approach for stationary base internal combustion engine mapping
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2020)
Engine control optimization, with its always growing complexity, is in permanent focus of engine researchers and developers all over the world. Automotive engines are dominantly used in dynamic conditions, but generally, ...
Evaluation of heating efficiency and thermal comfort in special purpose vehicle cabins
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2021)
The paper presents the integrated application of two methods during testing HVAC system efficiency in the cabins of HUMMER.1151A1 and OAR 1RL-128D offroad vehicles. Spatial measurements of change in air temperature per ...
Thermogravimetric study on the pyrolysis kinetic mechanism of waste biomass from fruit processing industry
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2020)
The detailed kinetic analysis of slow pyrolysis process of apricot (Prunus armeniaca L.) kernal shells has been estimated, under non-isothermal conditions, through thermogravimetric analysis and derivative thermogravimetry. ...
Modeling of gas parameters in the cylinder of the automatic gun during firing
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2020)
The change of gas parameters in the cylinder of the automatic gun has a great influence on the dynamics of the gun. Many factors have an influence on the gas parameters in the gas cylinder such as the diameter and position ...
