Research activities on inflow turbulence generation methods have been vigorous over the past quarter century, accompanying advances in eddy-resolving computations of spatially developing turbulent flows with direct numerical simulation, large-eddy simulation (LES), and hybrid Reynolds-averaged Navier-Stokes–LES. The weak recycling method, rooted in scaling arguments on the canonical incompressible boundary layer, has been applied to supersonic boundary layer, rough surface boundary layer, and microscale urban canopy LES coupled with mesoscale numerical weather forecasting. Synthetic methods, originating from analytical approximation to homogeneous isotropic turbulence, have branched out into several robust methods, including the synthetic random Fourier method, synthetic digital filtering method, synthetic coherent eddy method, and synthetic volume forcing method. This article reviews major progress in inflow turbulence generation methods with an emphasis on fundamental ideas, key milestones, representati...

流入湍流生成方法

在过去的四分之一个世纪中，流入湍流生成方法的研究活动一直很活跃，伴随着直接数值模拟、大涡模拟 (LES) 和混合雷诺平均 Navier-Stokes 对空间发展湍流的涡解析计算的进步。莱斯。弱循环方法植根于典型不可压缩边界层的尺度论证，已应用于超音速边界层、粗糙表面边界层和微尺度城市冠层 LES，并结合中尺度数值天气预报。合成方法起源于对均匀各向同性湍流的解析近似，已经扩展为几种稳健的方法，包括合成随机傅立叶方法、合成数字滤波方法、合成相干涡流方法、和合成体积强迫方法。本文回顾了流入湍流生成方法的主要进展，重点介绍了基本思想、关键里程碑、代表性……
