| 本文用数值求解流体力学基本方程组的方法（场模拟）建立了烟气运动的三维数理模型，比较详细地研究了三维离散传播辐射模型在烟气运动传热过程中的应用，揭示了烟气运动的一些典型规律，所得模拟结果基本合理。 |
| 英文摘要: |
| As we know,radiation is the major method of heat transfer in fire and combustionprocess comparing with conduction and convection,In this paper,one of the accurateradiation model -Discrete Transfer model has been established and verified.It is alsoemployed to simulate the hot smoke movement using the field modeling method based onthe basic equations of fluid mechanics by solving the distribution of hot smoke state pa-rameters and the k-εtwo-equation turbulence model with the modification of buoyan-cy. Some promising resultb of temperature and mass fraction distribution of hot smokehave been obtained. These resuIts have shown the whole process of smoke movementand revealed the relationbhip between smoke movement and convection,diffusion,windeffect. |
