Generalized collisional fluid theory for multi-component, multi-temperature plasma using the linearized Boltzmann collision operator for scrape-off layer/edge applications

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 V.M., Transport processes in multi-component plasma, Taylor Francis (2002)] 13N-moment scheme. First, differences directly, first approximation viscosity friction force compared. For coefficients, it found that they behave reasonably similarly small differences, but display substantial when high, both values. Furthermore, 21N-moment single-temperature provided al, seen higher than have even vicinity equal temperatures, especially calculations.
