“…Recent years have witnessed a growing interest in developing numerical methods suitable for computing mixture of fluid flows and in their efficient implementation to studying complex flow phenomena, (e.g., Chern et al, 1986;Karni, 1988Karni, , 1994Larouturou and Fezoui, 1989;Chargy et al, 1992;Abgrall, 1996;Shyue, 1998Shyue, , 1999Abgrall and Karni, 2001;Marquina and Mulet, 2003). Conservative Euler solvers for gas mixtures produce numerical errors and oscillations near contact discontinuities (Jenny et al, 1997).…”

“…Most of the recent works have been focused on the problems consisting of pure fluids separated by material interfaces (e.g., Chern et al, 1986;Karni, 1988;Miller and Puckett, 1996;Coquel et al, 1997;Fedkiw et al, 1999;Abgrall and Karni, 2001), or on the fluid flow mixtures regardless of mass diffusion effects, (e.g., Larouturou and Fezoui, 1989;Chargy et al, 1992;Karni, 1994;Abgrall, 1996;Ivings et al, 1997;Jenny et al, 1997;Shyue, 1998Shyue, , 1999Marquina and Mulet, 2003). Understanding the dynamics of fluids consisting of several fluid components is of great interest in a wide range of physical flows.…”

A computer code has been developed for numerical computation of compressible turbulent Navier-Stokes equations in general curvilinear coordinates, to solve binary perfect gas mixture flows. The prepared algorithm and the computer code are capable of modeling mixture effects in different fluid flows including viscous and mass diffusion effects. The Roe's numerical scheme is used to discretize the convective terms of governing fluid flow equations and simple upwinding method is used to discretize the equation of continuity of species. A complete model for mass diffusion which consists of ordinary, thermal and pressure terms is employed. The goal of this study is to investigate effects of viscosity, mass diffusion and especially thermal diffusion, on flow fields consisting of different mixtures. It is shown that the thermal mass diffusion can have profound effect on some flow fields, especially when the temperature gradient is not small. However, pressure mass diffusion can be negligible in the most of conventional problems.
