采用非稳态RANS方法结合Spalart-Allmaras湍流模型,对高雷诺数下被动控制的串列双圆柱静止绕流和流致振动进行数值计算。详细分析柱体受力、流致振动特性及尾流旋涡形态,结果表明双圆柱静止时,上游圆柱St随Re增加而增大,下游圆柱St先增大后减少,在Re=60000时达到最大值;双圆柱产生流致振动时,上下游圆柱的振幅率变化曲线出现三个不同分支,包括涡致振动初始分支、涡致振动上部分支和驰振分支,圆柱驰振时的最大振幅达到了2.8D。 The unsteady RANS method and the Spalart-Allmaras turbulence model are used to calculate the quasi-static flow and flow induced vibration of a tandem double-cylinder with passive control under high Reynolds number. The results show that when the double cylinder is at rest, the upstream cylinder St increases with Re increasing and the downstream cylinder St first increases and then decreases, reaching the maximum at Re = 60000 When the double cylinders produce flow-induced vibration, there are three different branches in the amplitude curve of the upper and lower cylinders, including the initial vortex-induced vibration branch, the vortex-induced vibration upper branch and the vibration-induced branch. 2.8D.
