Grad's method is used on the linearized Boltzmann collision operator to derive most general expressions for coefficients a multi-component, multi-temperature plasma up rank-2. In doing so, then get expressed as series sum of pure temperature and mass ratios multiplied by cross-section dependent Chapman-Cowling integrals. These collisional are compared previously obtained Zhdanov et al [Zhdanov ...

The motion of vortex sheets with surface tension has been analyzed in the setting of irrotational flows by Ambrose [1] and Ambrose & Masmoudi [2] in 2D, and by Ambrose & Masmoudi [3] in 3D. With irrotationality, the nonlinear Euler equations reduce to Poisson’s equation for the pressure function in the bulk, and the motion of the vortex sheet is decoupled from that of the fluid, thus allowing b...

The analytical theory of one dimensional, dispersion free miscible displacement of oil by injection gas with nc component has shown that: the MMP is the lowest pressure at which any one of the initial oil, injection gas or crossover key tie lines becomes critical, which means that its length approaches to zero. In this paper, we propose a method for a solving multi component syst...
