本文提出了一种谱强迫格式，用于在均匀各向同性湍流的直接数值模拟中获得统计上稳定的速度场。强迫方案的测试表明，强迫的细节并没有显着的影响上的小尺度结构的速度fields.Forced湍流模拟的时间步长的影响，和网格的空间分辨率，对计算。
A spectral forcing scheme is developed to provide the means to obtain statistically stationary velocity fields in direct numerical simulations of homogeneous, isotropic turbulence. Tests of the forcing scheme show that the details of the forcing do not have a significant effect on the small-scale structure of the velocity fields.Forced turbulent simulations are used to determine the effects of the time-step, and the spatial resolution of the grid, on the computations.
