【摘要】：利用蒙特卡洛法进行复杂物体表面之间的热辐射计算,采用小三角形单元贴合辐射源物体表面和接受辐射物体表面,将复杂表面之间的热辐射计算简化为小三角形单元之间的辐射计算。通过圆柱和水平微元面的辐射模型的验证计算表明,该方法求得的角系数与理论值的误差在5%以内,证明了这种方法的精确性。并将此方法用于圆锥形火焰与圆柱物体的表面辐射角系数的计算。
[Abstract]:The Monte Carlo method is used to calculate the thermal radiation between the surfaces of complex objects. The small triangle element is used to attach the surface of the radiation source and the surface of the object receiving the radiation. The calculation of thermal radiation between complex surfaces is simplified to that between small triangular elements. The error between the angular coefficient obtained by the method and the theoretical value is less than 5%, which proves the accuracy of the method. The method is applied to the calculation of the surface radiation angle coefficient between a conical flame and a cylindrical object.
