One-Dimensional Nonequilibrium Radiation-Transport Equation under Diffusion Approximation and Its Discrete Scheme

الملخص EN

Based on the nonlocal thermodynamic equilibrium state and large optical thickness of plasma, we establish one-dimensional nonequilibrium radiation-transport equation from diffusion approximation.

Through finite volume method, the discrete scheme of radiation-transport equation and the conditions for its definite solution are proposed.

The reliability of radiation-transport equation and its discrete scheme is validated.
