| 摘 要： | 发展一种配置点谱方法,计算包含半透明各向异性散射介质的圆柱系统中的辐射传热.介质具有梯度折射率,并且散射反照率随空间位置变化.通过与精确解或其他方法的结果对比,验证配置点谱方法的准确性.结果表明:配置点谱方法仅采用少量的节点数就可以得到准确的辐射热流量.

| Abstract: | We develop a collocation spectral method (CSM) to address radiative transfer in a semitransparent anisotropic scattering cylindrical medium with graded index and space-dependent albedo. Accuracy and validity of the method is verified with exact solutions available in literature and other methods. CSM is found effective in obtaining radiative flux in graded index medium. And few nodes are enough to obtain accurate results. |
