The radiation problem in one-dimensional participating media between two concentric spheres is solved by mapping the concentric spherical domain into the plane-parallel domain, where the radiative rays propagate along curved paths. The computational plane-parallel domain is discretized into slices with constant radiative properties and the angular domain for each control volume is discretized into variable polar angles. To validate the accuracy of the present method, comparisons are made with the previous studies in literature.

共形映射与变离散坐标法相结合求解同心球介质辐射传热问题

通过将同心球域映射到平面平行域中，解决了两个同心球之间的一维参与介质中的辐射问题，其中辐射线沿着弯曲的路径传播。计算平面平行域被离散为具有恒定辐射特性的切片，每个控制体积的角域被离散为可变极角。为了验证本方法的准确性，与文献中的先前研究进行了比较。
