Abstract
The transport processes in edge (collisional) plasmas of axially symmetric tokamaks with elongated cross sections and with toroidal plasma flows are considered. The poloidal velocity of particles and the ion heat flux are derived. It is shown that toroidal plasma flows, induced by neutral beam injection or radio frequency waves, can be used to control the poloidal plasma velocity and ion heat conductivity in a wide range of these values. The ellipticity allows one to achieve these effects at smaller values of the toroidal Mach number.
