Abstract
A previous formulation of neoclassical transport for an axisymmetric plasma with arbitrary toroidal rotation is generalized to plasmas with impurity ions. Calculations in the banana regime for a two‐ion species plasma for large aspect circular flux surfaces show significant enhancement of both particle and heat fluxes. The viscous part of the momentum flux remains small. A more detailed treatment of the electron equations reveals the importance of an assumption relating to the balancing of the toroidal torques on the electron fluids which is likely to require modification in practical situations.
