Abstract

It is shown that suction nonuniformities may induce a new instability of the Blasius boundary layer that results in the generation of streamwise vortices. Addition of a uniform suction is not effective in controlling this instability. It is shown that nonuniformities of surface blowing may induce a similar instability and that the characteristics of this instability are also little affected by the magnitude of the blowing. Finally, it is shown that suction nonuniformities appear to have a minimal effect on the traveling (Tollmien-Schlichting) wave instability. © 2001 American Institute of Physics.
