Buiding fire simulation
I use the software Fluent 6.0 to calculated the fire in the enclosure. The fire is taken as heat source. I met a problem about fire source. When it is taken a heat volume source, only the heat density is given, but the heat transfer by free convection caused by the increase of air temperature is very slowly. If we taken it as hollow cavity and give the heat flux of the surface, the calculation would not converge. Who can give some suggestions on fire simulation for me? Thanks.
