Abstract

The behaviour of the near-field region of a vertical rectangular jet of aspect ratio 4:1 controlled by a rotating cylinder placed on the jet major-axis is investigated experimentally using a new design facility. The objective is to investigate flow control strategies of a rectangular jet based on instability manipulation. It is found experimentally that the controlled jet exhibits similar behaviour to the one described theoretically and numerically by Hammond & Redekopp (1997a, b) on bluff-body wakes with higher control efficiency when the global instability mode is suppressed.
