T1 Viscous and Inviscid Solutions of Some Gas Mixture Problems JF Heat Transfer Research JO HTR YR 2011 FD 2011-11-16 VO 42 IS 3 SP 233 OP 250 K1 viscous flow K1 inviscid flow K1 gas mixture K1 kinetic theory K1 multifluid model AB The aim of the present paper is to simulate some gas mixture problems in the context of a converging-diverging nozzle. A recently proposed multifluid model is utilized for the description of the flow fields. The model consists of separate balance equations for each component species of the system. Thereby, it provides details of the flow fields for each of the constituents separately, which is not available in other continuum descriptions. The new model also computes transport coefficients from some kinetic relations without the requirement of being input externally. Moreover, it automatically describes diffusion processes excluding the use of any coefficients for ordinary, pressure, and thermal diffusion that are generally required in Navier-Stokes computation of gas mixture flows.
During the analysis of the current mixture problems, the viscous as well as the inviscid forms of the multifluid balance equations are solved and the corresponding results are compared with those of the Navier-Stokes and Euler equations.
