Longitudinal transport coefficients in a magnetized hydrogen plasma with impurity admixtures
Study of the plasma-wall interaction in magnetic fusion devices requires transport equations for a plasma consisting of hydrogen and low Z impurity admixtures such as carbon and oxygen. For high impurity concentrations a strong collisional coupling exists between the various ion species, and the plasma behaviour should then be described by multifluid equations. A summary is given of the classical longitudinal diffusion, heat transfer and viscosity coefficients for a plasma mixture of hydrogen and a single impurity element in its various charge states. The results are presented within Grad's 21 moment approximation, which yields the same accuracy in the transportation coefficients as Braginski's Sonine polynomial expansion method.
