Transport synthetic acceleration for the solution of the one-speed nonclassical spectral S-N equations in slab geometry

扫码查看
The nonclassical transport equation models particle transport processes in which the particle flux does not decrease as an exponential function of the particle's free-path. Recently, a spectral approach was developed to generate nonclassical spectral S-N equations, which can be numerically solved in a deterministic fashion using classical numerical techniques. This paper introduces a transport synthetic acceleration procedure to speed up the iteration scheme for the solution of the monoenergetic slab-geometry nonclassical spectral S-N equations. We present numerical results that confirm the benefit of the acceleration procedure for this class of problems. (C) 2021 Elsevier B.V. All rights reserved.
