设有一炉膛空间 ,其中充满吸收性和辐射性气体 ,炉壁为不透热材料 ,忽略对流传热和传导传热。采用区域法 ,即将整个系统划分为 m个表面和 n个空间 ,每个区域中的辐射热交换特性值为常数。按照通常的区域法 ,计算辐射热交换时要引入角度系数的概念 ,这是造成计算困难的一大问题 Has a furnace space, which is full of absorptive and radioactive gases, furnace wall is impermeable material, ignoring the convective heat transfer and conduction heat transfer. Using the region method, the entire system is divided into m surfaces and n spaces, and the radiation heat exchange characteristic values ​​in each region are constant. According to the usual area method, the concept of introducing angle coefficients when radiative heat exchange is introduced is a major problem that causes computational difficulties
