摘要
为验证提出的离散坐标算法 ,采用了一个带内热源的平行平板测试问题和两个二维吸收 各向同性散射测试问题 .数值试验表明本方法能够以较少的离散方向和较短的计算时间来获得具有比较精确的任意方向上的辐射强度 .
In order to verify the proposed new algorithm, one parallel-plate test problem with one inner heat source and two 2-D absorbing-isotropically scattering problems were presented. Numerical tests showed that the present algorithm was able to predict radiation intensities in arbitrary directions with fewer discrete directions and shorter computational time.
