摘要

本文建立了包含吸收、发射和散射介质的二维腔体中瑞利-贝纳德热对流传递的气体动力学Bhatnagar-Gross-Krook (BGK)模型，其中流场和温度场由两个耦合晶格玻尔兹曼方法(LBM) BGK模型描述。采用控制体积有限元法求解热辐射问题。研究了带辐射的二维瑞利-贝纳德热对流问题，并将数值结果与现有的一些基准解进行了比较，结果吻合较好。

Transient Rayleigh-Bénard Thermal Convection With Radiation Heat Transfer in Participating Media Using the Control Volume Finite Element Method (CVFEM) and Lattice Boltzmann Method

In this paper, a gas-kinetic Bhatnagar-Gross-Krook (BGK) model is constructed for the Rayleigh-Benard thermal convection transfer in a two-dimensional cavity containing an absorbing, emitting, and scattering medium, where the flow field and temperature field are described by two coupled Lattice Boltzmann Method (LBM) BGK models. Heat radiation is solved using the Control Volume Finite Element Method (CVFEM). The two-dimensional Rayleigh-Benard thermal convection with radiation is studied and numerical results are compared with some available benchmark solutions and a good agreement has been observed.
