| Abstract |
Boundary layers exposed to adverse pressure gradient are known to be very unstable with respect to traveling wave instability. This instability can be eliminated through application of wall suction. It is shown that when suction distribution is not uniform, another type of instability giving rise to streamwise vortices may occur. 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 non-uniformities of surface blowing can induce similar vortex-type instability. |
