A diffusion accelerated Sn transport method for radiation transport on a general quadrilateral mesh
We present the development of a diffusion accelerated Sn transport method for the solution of temperature coupled radiation flow problems on a spatial mesh of arbitrary quadrilaterals in R-Z geometry. The diffusion acceleration equation is derived from the diamond-like transport spatial discretization. The effectiveness of the DSA method is shown on an example calculation and also computation times are indicated. 3 refs., 3 figs.
