Abstract: Aiming at the problem of thermal environment numerical simulation of buildings, this paper proposes a new research method of thermal environment numerical simulation of high-rise buildings based on Rosseland radiation model. First of all, analyse the wind flow characteristics of the thermal environment around the building to obtain the total heat value. Secondly, the energy conservation law equation, momentum conservation law equation and mass conservation law control equation of hot gas fluid flow are constructed. Finally, Rosseland radiation model is introduced to obtain heat flux and output the numerical simulation results of thermal environment. The results of performance comparison show that the proposed simulation method can get accurate thermal environment simulation results without being affected by seasonal temperature changes.
