Rotational Suppression of Pfirsch-Schlüter Ion Thermal Conductivity for a Plasma

Ion thermal conductivity for a tokamak plasma in the collisional regime with arbitrarily large toroidal rotation is calculated from Braginskii's equations. It is found to decrease to the classical value as ${\nu }_{\mathrm{ii}}^{-1\mathrm{}}$ for high enough collisionality.
