摘要
引入了表面发射率、几何平均透过率等矩阵参量来描述有介质参与的辐射换热体系 ,基于介质内辐射传递方程以及体系的辐射能量平衡方程组 ,提出了求解介质参与辐射体系的矩阵直接解法 ,导出了直接计算净辐射换热量及温度的显式矩阵方程·
Three matrices of geometric-mean transmittance, emissivity and area were introduced to describe the radiation heat transfer in an enclosure with homogeneous participating media. Based on the radiative transfer equation and the radiative energy equation of the media-participating radiation system, direct matrix expression method for solving radiation heat transfer is presented. The solution is quite easy by finding out the inverse matrices. The heat transfer rate of the system is given out by the solution. The explicit matrices equations can also reveal the relations between the net radiation fluxes of the surfaces and temperatures of the media gas accurately.
