Buffeting Prediction of a Square Cylinder with Inflow Turbulence

Abstract:

It is known that the fluctuating structural load is caused by turbulent eddies flowing past or impinging upon the structure in case of turbulence buffeting. The prediction of the response of a structure to turbulence buffeting may be very important. In this paper the buffeting response of square cylinder with constant damping ratio (5%) based on FSI theory proposed by Zhe Liu [6] is simulated. And the movement of bluff body is controlled in the across-flow direction, and two types of inlet boundary conditions are considered to compare the different influence of them on the flow around the square cylinder, one is the steady inlet boundary and the other is the unsteady one.
