Summary
In the frame of an extended kinetic theory for gas mixtures, the scattering kernels appearing in the elastic scattering collision terms are explicitly evaluated for any value of the mass ratio between the colliding particles. Their expressions are then used in order to obtain the relevant moment equations needed for the solution of the generalized transport problem. A Laguerre series expansion for the polynomial reconstruction of the distribution functions is finally derived, and the influence of different physical effects is briefly discussed.
