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

General metrics of large aspect ratio tokamaks is used in the paper. General expressions for the neoclassical poloidal plasma rotation V-2(theta) and radial ion heat flux Gamma(Ti) are obtained. Their dependence 2 on the squared Mach number alpha = U-zetai(2)/c(5)(2) is analyzed (here U-zetai is the ion toroidal velocity and c(s) is the sound velocity, respectively). Some interesting peculiarities of this dependence are emphasized.
