The method developed uses random forcing with constant power input for two-dimensional gyrokinetic turbulence simulations to study stationary plasma turbulence. Through this method, turbulence is demonstrated in both large-scale fluid and small-scale kinetic regimes, successfully reproducing theoretically predicted scaling laws in a statistically steady state.
A method of random forcing with a constant power input for two-dimensional gyrokinetic turbulence simulations is developed for the study of stationary plasma turbulence. The property that the forcing term injects the energy at a constant rate enables turbulence to be set up in the desired range and energy dissipation channels to be assessed quantitatively in a statistically steady state. Using the developed method, turbulence is demonstrated in the large-scale fluid and small-scale kinetic regimes, where the theoretically predicted scaling laws are reproduced successfully.
