EFFECT OF SUBSONIC TOROIDAL FLOWS ON PLASMA POLOIDAL ROTATION AND IONHEAT-CONDUCTIVITY IN COLLISIONAL PLASMAS OF ELONGATED TOKAMAKS

The ion poloidal rotation and heat conductivity in collisional plasmas of axially-symmetric tokamaks with elongated cross-sections and with subsonic toroidal plasma flows are considered. It is shown that subson ic toroidal plasma flows, induced by neutral beam injection or radio f requency waves, can strongly affect the poloidal plasma velocity and i on heat conductivity in collisional plasmas of tokamaks. The transport coefficients also depend on the tokamak ellipticity parameter which, in combination with the Mach number, allows to operate transport proce sses at smaller values of the toroidal Mach number. The importance of taking into account the ion-electron heat exchange and electron temper ature toroidal perturbations to find ion temperature toroidal perturba tions is demonstrated.
