| Abstract: | 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. |
