- Abstract
- ONLY ABSTRACT IN ENGLISH As we know, radiation is the major method of heat transfer in fire and combustion process comparing with conduction and convection. In this paper, one of the accurate radiation model - discrete Transfer model has been established and verified. It is also employed to simulate the hot smoke movement using the field modeling method based on the basic equations of fluid mechanics by solving the distribution of hot smoke state parameters and the k - e two - equation turbulence model with the modification of buoyancy. Some promising results of temperature and mass fraction distribution of hot smoke have been obtained. These results have shown the whole process of smoke movement and revealed the relationship between smoke movement and convection, diffusion, wind effect.
