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, ...
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 ...
Heat and mass transfer during contact drying of a sheet of moist material
(Thermal Science, 1999)
Observed are the processes of heat and mass transfer inside the layer (sheet) of wet material placed on flat heating surface of constant, but variable and controllable temperature, and exposed, from above, to the horizontal ...

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 ...
