摘要

通过在势流场中嵌入有限数目的点涡来代表局部有旋区域连续分布的涡量

在拉格朗日框架下应用离散涡方法求解非定常涡量方程

从而有效模拟了高雷诺数下不同直径串列圆柱绕流脱落旋涡的动态演化过程

并分析了流场中大尺度旋涡相干结构对前后圆柱受力的影响.结果表明

流场中的小尺度旋涡会被大尺度旋涡卷吸

形成涡量强度更大的旋涡.当大圆柱在前、小圆柱在后布置时

大圆柱的升、阻力系数受影响较小

大圆柱阻力系数基本保持不变

小圆柱阻力系数平均值较小但振幅波动较大

大圆柱的升力系数波动较大

大、小圆柱的升力系数的平均值都基本为0; 当小圆柱在前、大圆柱在后布置时

大圆柱阻力系数振幅增大而平均值降低

小圆柱阻力系数振幅减小而平均值增大

大、小圆柱的升力系数趋向于一致

平均值仍然都基本为0.

Abstract

A discrete vortex model has been developed to solve the unsteady vortex dynamics equation under the Lagrangian frame

in which the point vortex was used to represent the location where vorticity concentrated. The transient evolution of vortex shedding process behind two tandem cylinders with different diameters was simulated effectively and the influence of large-scale coherent structure in the flow field on the two cylinders was analyzed. It is found that small vortices will be entrained by the large-scale coherent structure to form larger vortices with higher vorticity. When the front cylinder is big and the rear one is small

there is little change on the drag and lift coefficients of the big cylinder compared with the case of single cylinder. The drag coefficient amplitude of the big cylinder will nearly keep constant. The drag coefficient amplitude of the small one will increase while the average value will be close to zero. The lift coefficient amplitude of the big one will increase and the average value of both cylinders will be close to zero. When the front cylinder is small and the rear one is big

the amplitude of drag coefficient of the big one will increase and the average value will decrease while the amplitude of the small one will decrease and the average value will increase. The lift coefficients of the two cylinders tend to be the same with each other and the average values are close to zero.
