Reconstruction of the aero-mixture channels of the pulverized coal plant of the 100 MW power plant unit
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2011)
After the last revitalization of thermal power block of 100 MW in TPP 'Kostolac A', made in the year 2004, during the operation of the plant, pulverized coal deposition often occurred in horizontal sections of the aero-mixture ...
The effect of bowl-in-piston geometry layout on fluid flow pattern
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2011)
In this paper some results concerning the evolution of 3-D fluid flow pattern through all four strokes in combustion chambers with entirely different bowl-in-piston geometry layouts ranging from 'omega' to 'simple cylinder' ...
Some subtleties concerning fluid flow and turbulence modeling in 4-valve engines
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2011)
In this paper some results concerning the structure and evolution of fluid flow pattern during induction and compression in 4- valve engines with tilted valves were presented. Results were obtained by dint of multidimensional ...
The possibilities for measurement and characterization of diesel engine fine particles: A review
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2011)
This review paper considers possible instrumentation for diesel engine fine particles exhaust emission evaluation. The modern diesel engines have extremely low particles emission almost at the level of measurement error ...
Numerical study of transient three-dimensional heat conduction problem with a moving heat source
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2011)
A numerical study of transient three-dimensional heat conduction problem with a moving source is presented. For numerical solution Douglas-Gunn alternating direction implicit method is applied and for the moving heat source ...
Rectified ethanol production cost analysis
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2011)
This paper deals with the impact of the most important factors of the total production costs in bioethanol production. The most influential factors are: total investment costs, price of raw materials (price of biomass, ...
Thermal history and stress state of a fresh steam-pipeline influencing its remaining service life
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2011)
The service life of thick-walled power plant components exposed to creep, as is the case with pipelines of fresh- and reheated steam, depend on the exhaustion rate of the material. Plant operation at elevated temperatures ...
Thermal stress analysis of a fiber-epoxy composite material
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2011)
Paper presents stress calculation in the stationary temperature domain for a hybrid structure with standard epoxy-carbon fiber composite and metallic part, showing different thermal behavior. The thermal stress analysis ...
