VANT. Ser.: Mat. Mod. Fiz. Proc 2017. Вып.3. С. 39-50.

Solution of the spectral radiation transport equation is one of the challenging problems in the transport theory due to a high dimensionality of space. This is the reason for using different approximations, which allow reducing the given transport problem to a simpler problem. The paper describes the model for the heat transport simulation in the multigroup quasi-transport approximation for a 2D geometry, which has been developed by introducing multiplying factors for path in the diffusion approximation. The model problem solution results are compared.

Keywords: radiation transport, quasi-transport approximation.
