A quick, simplified approach to the evaluation of combustion rate from an internal combustion engine indicator diagram
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2008)
In this paper a simplified procedure of an internal combustion engine in-cylinder pressure record analysis has been presented. The method is very easy for programming and provides quick evaluation of the gas temperature ...
Reduction of carbon monoxide emission from a solid-fuel thermo-accumulation furnace
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2006)
Many households in Serbia, using electric thermo-accumulation furnaces for heating, have been forced to find an alternative solution, due to a significant increase in electricity prices during the last decade. A possible ...
Research and development of efficient, environmentally improved household gas appliances
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2006)
An experimental research and analysis of performance of three domestic house hold gas appliances was carried out. The objective of this work, based on the conducted analysis of the research data, was to improve the appliances’ ...
An increase of hydro-aggregate's installed power and efficiency factor before the revitalization phase
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2006)
The revitalization of hydro-aggregates should be performed before the life-time expiry of most their parts. But, as in our practice aggregates have been under exploitation much longer then theoretical life-time advices ...
Fluid boundaries shaping using the method of kinetic balance
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2006)
Fluid flow in curved channels with various cross-sections, as a common problem in theoretical and applied fluid mechanics, is a very complex and quite undiscovered phenomenon. Defining the optimum shape of the fluid flow ...
Simulations of the kettle reboiler shell side thermal-hydraulics with different two-phase flow models
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2006)
A computational fluid dynamics approach is presented for the simulation and analyses of the kettle reboiler shell side thermal-hydraulics with two different models of two-phase flow – the mixture and two fluid model. The ...
Investigations of combustion process in combined cooker-boiler fired on solid fuels
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2006)
The aim of the investigation was to make some reconstructions on the existing stove used for cooking and baking and to obtain the combined cooker-boiler which will fulfill the demands of European standard EN 12815. ...
Development of the heating system using geothermal energy
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2006)
The paper presents the results achieved by the project financed by Ministry of Science and Environmental Protection of Serbia during the period 2003-2005. The purpose of the project was determination methodology for designing ...
Rapid pyrolysis of Serbian soft brown coals
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2009)
Soft brown coals of the open coal fields of Kolubara and Kostolac are the main domestic energy sources of Serbia. This paper presents the results of investigations on rapid devolatilization of these two coals which have ...
Influence of running conditions on resonant oscillations in fresh-air ventilator blades used in thermal power plants
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2009)
High frequency cyclic load of fresh air supply to ventilator blades in thermo energetic facilities can cause the occurrence of fretting in the pressed overlap of ventilator shaft and socket. These loads can be generated ...
