Improved angular discretization and error analysis of the lattice boltzmann method for solving radiative heat transfer in a participating medium

摘要

In this paper, some improvements to the lattice Boltzmann method (LBM) for solving radiative heat transfer in a participating medium are presented and validated. Validation of the model is performed by investigating the effects of spatial and angular discretizations and extinction coefficient on the solution. The error analysis and the order of convergence of the scheme are also reported
