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 ...
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 ...
