“…In many practical flows involving pollutant dispersion, chemical processing, and combustor mixing and reaction, mass and momentum transport within multispecies fluids play an important role. Recent years have witnessed a growing interest in developing numerical methods suitable for computing multicomponent flows as well as their efficient implementation in studying complex flow phenomena (e.g., Chern et al, 1986;Karni, 1988Karni, , 1994Garzo et al, 1989;Larouturou and Fezoui, 1989;Chargy et al, 1992;Abgrall, 1996;Shyue, 1998Shyue, , 1999Lian and Xu, 1999;Abgrall and Karni, 2001;Marquina and Mulet, 2003;Luo and Grimanji, 2003;Kamali et al, 2005).…”
