Neoclassical ion transport in the edge of axially-symmetric arbitrary cross-section tokamak with plasma subsonic toroidal flows

Abstract

General metrics of large aspect ratio tokamaks is used in the paper. General expressions for the neoclassical poloidal plasma rotation Viθ and radial ion heat flux left ceilingΓTi are obtained. Their dependence on the squared Mach number α = Ui2/cs2 is analyzed (here Uζi is the ion toroidal velocity and cs is the sound velocity, respectively). Some interesting peculiarities of this dependence are emphasized.
