Abstrakt

A numerical simulation of combined natural convection and radiative heat transfer is presented. The Radiation Element Method by Ray Emission Model (REM2) and the Discrete Ordinates Radiation Element Method (DOREM) are used to solve the radiative heat transfer. The Large Eddy Simulation (LES) is used for the simulation of turbulent natural convection. Benchmark tests are conducted by comparing the results with experimental data. The effects of nongray radiative heat transfer on convection are scrutinized in a smoke-filled fire room. The numerical simulations show that radiative heat transfer plays a significant role on the flow patterns and temperature distributions in an enclosure containing participating medium.
