The Numerical Method Analysis of the Natural Convection and Heat Transfer in the Room with Heat Transfer of Material and Radiation Coupled in Natural Convection

In this paper, the additional source term method is applied to the flow and heat transfer problems with radiation. According to the solid radiation surface's situation, the effects of radiation on heat transfer can be divided into two cases. One is that the solid wall is in the solver region. The conduction, heat transfer and radiation act together in the interface between solid and liquid. This is the problem of combined conduction, heat transfer and radiation. The other is that the solid wall is the boundary of the solver region. The radiation heat is used as boundary condition. The solution method is different to them.
