Abstract

Two-dimensional simulations are used to demonstrate the existence of two different amplitude regimes to control laminar separation bubbles with periodic zero-mass-flux wall jets. One is based primarily on a shear-layer instability found using low-amplitude forcing. The minimum bubble length is obtained for a Strouhal number approximately equal to 0.018, based on a properly defined momentum thickness. Higher forcing is found to create large vortices, which are responsible for very effective control. A relation is presented between the forcing parameters and the size of the vortices. These estimates are then used to explain the range of effective frequencies to control the separation bubble.
