Numerical Simulation on Combined Natural Convection and Radiation Heat Transfer With a Scattering Medium in a Square Cavity

Keywords： radiation heat transfer , hybrid grids , finite volume method , isotropic scattering

本文在自主软件GTEA基础上,针对封闭方腔内参与性介质的辐射与自然对流耦合换热进行模拟,计算结果与文献中经典算例结果吻合较好.并分析了普朗克数和介质散射反照率的变化对方腔内温度和速度的影响,结果表明:随着普朗克数的减小,增强了辐射换热的影响;考虑各向同性散射介质时,随着散射反照率的减小,中心处的温度有所增大,靠近绝热壁面处,速度U的变化更剧烈.
