I2-S5 · On the Excitation of Zonal Flows by Wave Particle ResonancesWeiland, Jan1) Abstract Excitation of zonal flows by ion temperature gradient driven modes has been studied using both fluid and kinetic models. Previous fluid derivations have shown that a strong excitation of zonal flows occurs through the nonlinearity in the energy equation and is enhanced by the fluid magnetic drift resonance. Thus a new derivation has been made by nonlinear kinetic theory, confirming that a strong excitation occurs through the kinetic magnetic drift resonance. Fluid and kinetic results are compared.
