二维复杂系统内直接交换面积的计算

Evaluation of Direct Exchange Areas for a Two Dimentional Complex Structure Enclosure with Participating Media

用均匀离散射线法计算了二维分段、几何形状复杂（内含遮蔽效应）、及有非均质参与的复杂系统的直接交换面积．结果表明该方法计算精度高。

The previously published uniform deterministic discrete method is applied to evaluating the direct exchange areas for a complex geometrical enclosure with partipating media,and the interests of shelters within the enclosure are considered. The calculation results show that the reciprocity and summation rules of direct exchange areas based on radiative balance and conservation can be obtained with high accuracy but less computer cost.
