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.

用于二维陀螺动力学模拟的恒定功率输入的随机强迫

为研究稳态等离子体湍流，开发了一种用于二维旋动湍流模拟的恒定功率输入的随机强迫方法。强迫项以恒定速率注入能量的特性使得湍流能够在所需范围内建立，并且能量耗散通道能够在统计稳定状态下进行定量评估。使用所开发的方法，在大尺度流体和小尺度动力学状态下证明了湍流，成功地再现了理论上预测的比例定律。
