Improving structure dynamic behaviour using a reanalysis procedures technique
(Univ Osijek, Tech Fac, Slavonski Brod, 2013)
The present paper deals with the problem of improving dynamic characteristics for a sub-structure of bucket wheel excavator. The procedure is concerned with the analysis of the distribution of potential and kinetic energy ...
determining the reliability function of the thermal power system in power plant "nikola tesla, block b1"
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2015)
Representation of probabilistic technique for evaluation of thermal power system reliability is the main subject of this paper. The system of thermal power plant under study consists of three subsystems and the reliability ...
Influence of application of Hottel's zonal model and six-flux model of thermal radiation on numerical simulations results of pulverized coal fired furnace
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2012)
Difference of results of numerical simulation of pulverized coal fired furnace when mathematical models contain various radiation models has been described in the paper. Two sets of numerical simulations of pulverized coal ...
