扩散综合加速收敛方法在离散节块输运方法中的应用

Application of the Diffusion Synthetic Acceleration Technique to the Discrete Nodal Transport Method

本文介绍了在一、二维直角坐标的离散节块输运方法（ＤＮＴＭ）中采用扩散综合加速（ＤＳＡ）收敛的理论、方法和计算公式，并给出了一些数值结果，以了解其加速效果。

In this pspethe diffusion synthetic acceleration(DSA)technique is applied to the discrete nodal transport methd(DNTM)in the one and two-dimensional cartesian geometries. Aseries of test problems have been calculated.The numerical results verify that the DSA method has very high computational efficiency.
