摘要：

Wave-induced flows are calculated from high-resolution electromagnetic field calculations with either a compressible Reynolds stress or a second-order kinetic pressure model for the radio frequency forces. Results show that electron 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 typical of plasma-heating experiments.
