| 摘 要： | １引言工程上对炉内三维辐射换热的计算已越来越重视，较为精确的计算方法是Ｈｏｔｔｅｌ的区域法［１，２］和ＭｏｎｔｅＣａｒｌｏ方法［３］，但两者都有一定的局限性而得不到广泛应用，原因如下：对区域法，由于计算区域间直接辐射交换面积时需求解多重积分，在计算时...

| Abstract: | Radiative heat transfer is the dominant mode of heat transfer in high temperaturecombustion furnace. In this paper a hybrid method (combined Monte Carlo method andZone method) is presented to analyse radiative heat transfer of absorbing-emitting- scatteringmedia in three dimensional enclosed rectangular, and is proved its accuracy by comparingthe calculation results with exact results from classical Zone method. |
