合成射流对串列双圆柱涡致振动的控制效果
Control effects of synthetic jets on the Vortex Induced Vibration of two tandem circular cylinders
摘要
Abstract
The effect of synthetic jets on the Vortex Induced Vibration(VIV)of two tandem circular cylinders was studied by numerical simulation.The effects of reduced velocity and the momentum co-efficient of the resultant jet on the shedding process,displacement amplitude and lift resistance of the downstream cylinder vortex were analyzed.In the study,the incoming Reynolds number Re=150,the position angle α=45°,and the spacing ratio is 4.The numerical results show that the horizontal synthetic jet can effectively suppress the vibration of the downstream cylinder and reduce the oscilla-tion amplitudes up to 80.48%.Under the control of the horizontal synthetic jet,the width between the two rows of trailing vortices shed by the downstream cylinder is obviously reduced.When the mo-mentum coefficient Cu increases from 2 to 4,the inhibition effect becomes more obvious.关键词
