摘要：

The objective of the present study was to investigate the suppression of the fluid forces acting on a circular cylinder by controlling the flow around it. Flow control was established by introducing a fine flat plate in the neighborhood of the main cylinder. Measurements were carried out with variation of the position and attack angle of the flat plate at a Reynolds number of 6.5 x 10(4). The time-averaged and fluctuating fluid forces were examined to estimate the magnitude of the reduction and to identify the optimum position of the control flat plate in reduction the fluid forces. Furthermore, the mechanism of the flow control, the nature of the controlled wake, the stability of the flow control and the relationship between the characteristics of the controlled fluid forces and behavior of the wake were discussed in detail. Then, the applicability of the present method reduction of the fluid forces and suppression the vortex shedding was evaluated
