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。计算结果对于分析一类管道中热和动量输运现象均有普遍指导意义。

Abstract: It presents 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 numerical results presented can also be used to predict thermal conductivity and diffusion and momentum transport phenomena in the kind of duct.

Key words: unstructured triangular meshes, finite volume method, non-parallel-wall channel, convection
