Abstract

This report presents the numerical results concerning the longitudinal ion viscosities, heat conductivities and thermal diffusion ratios in magnetised D-He and H-C plasmas within Grad's 21 moment approximation. Calculations taking full account of the finite mass ratio m(+)/m(z) between hydrogen (deuterium) and impurity ion mass are compared with those for values of m(+)/m(z) much less than 1. As expected, the largest discrepancies between exact and approximate results (with respect to the mass ratio) arise for D-He plasmas. It is shown that the approximate formula for the impurity ion heat conductivity has to be extended to correct previous deficiencies.
