摘要/Abstract

摘要： 用离散传递法计算辐射换热量，然后反算求解辐射全交换面积，计算过程方便可行.利用降维后的离散传递法计算了二维封闭体系的辐射全交换面积，与基本算法计算结果的比较表明该算法能够在保证计算精度的前提下大幅度减少所耗机时，同时计算结果很好地满足了全交换面积的互换性和完整性原则，这也进一步证明了离散传递法是求解辐射全交换面积的一种好方法.

Abstract: Total radiative exchange areas are resolved inversely with the radiative transfer fluxes obtained by the discrete transfer method (DTM), which can be easily performed. The DTM using the dimensionality reduction method is used to calculate the total radiative exchange areas in a two-dimensional enclosure. Compared to the basic zone method, the method can decrease CPU time greatly with enough accuracy. The results also fully satisfy the reciprocity and integrality of total radiative exchange areas, which shows that DTM is a better method for calculating the total radiative exchange areas.
