摘要
利用有限单元法离散求解辐射传递方程和能量控制方程.分别计算了边界为黑体和灰体条件下矩形吸收、发射、各向同性散射介质内的平均入射强度和温度分布,并同蒙特卡罗法(M C法)计算结果进行了比较.
The finite element method is applied to solve the radiative heat transfer equation and energy conservation equation discretely. This paper provides an exact solution of the mean incident intensity and the temperature distribution in a rectangular geometry in a absorbing, emitting, isotropically scattering media enclosed by black and gray diffuse surfaces. The validity of this method is examined by comparing the present results with the those available of Monte Carlo simulation (M-C). Numerical results show that the present method can satisfactorily predict the radiation transfer.
