摘要
首次将无结构三角网格的有限体积方法和压强连接半隐式算法相结合 ,用于求解非平行壁管道中的热对流问题 .并由此分析了化学汽相淀积薄膜生长的均匀性问题 .
It present a new upwind scheme on unstructured triangular meshes. The discretization of three conservation equations for mass,momentum and heat including thermodiffusion is performed using the upwind finite volume method.The two- dimensional mathematical model is used on the numerical study of convective phenomena in non- parallel- wall channels. Similarly,the numerrical results presented can also be used to predict thermal conductivity and diffusion ang momentum transportphenomena in the kind of duct.
