Random forcing with a constant power input for two-dimensional gyrokinetic simulations
Ryusuke Numata
Abstrak
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 to set up turbulence in the desired range and to quantitatively assess energy dissipation channels in a statistically steady state. Using the developed method, turbulences in the large scale fluid and small scale kinetic regimes are demonstrated, where the theoretically predicted scaling laws are successfully reproduced.
