Wave-induced momentum transport and flow drive in tokamak plasmas

Wave-induced flows are calculated from high-resolution electromagnetic fiel d calculations with either a compressible Reynolds stress or a second-order kinetic pressure model for the radio frequency forces. Results show that e lectron Landau damping and magnetic pumping, by themselves, do not lead to significant poloidal flow as long as there is Little net input of momentum by the wave. But ion-cyclotron damping of either fast magnetosonic waves or ion-Bernstein waves can drive significant poloidal flows at power levels t ypical of plasma-heating experiments. [S0031-9007(99)08584-1].
