Abstract

Boundary layers exposed to an adverse pressure gradient are known to be very unstable with respect to traveling wave instability. This instability can be eliminated through the application of wall suction. It is shown that when suction distribution is not uniform, another type of instability may occur, giving rise to streamwise vortices. It is further shown that an increase of uniform suction is not an effective method for control of this instability. Finally, it is shown that nonuniformities of surface blowing can induce similar vortex-type instability.
