Abstract

The Lattice Boltzmann Method (LBM) is applied to solve a multiphysics system that includes radiative/neutron transport equation coupled with heat conduction equation (including nonlinear heat source). Two types of boundary conditions, zero-incoming neutrons/photons and gray-diffuse surface, are considered. One-way and two-way couplings are implemented using LBM. The results are compared with those obtained using the finite difference method (FDM). In addition to a constant thermal conductivity in the diffusion equation, multiphysics problem is also formulated for temperature-dependent thermal conductivity. It was found that for the coupled heat conduction and neutron transport problems studied in this work, the LBM is at least 7 times faster than the FDM.
