Abstract

Time dependent ion parallel viscous force in the banana regime with arbitrary inverse aspect ratio ∈ is calculated using the eigenfunction approach. The flux surface averaged viscosity is then used to study the relaxation process of the poloidal rotation which leads to oscillatory relaxation behavior. The relaxation rate vp is found approximately proportional to vii/∈ (where vii is the ion collision frequency and ∈ is the inverse aspect ratio).
