Abstract

Effects of wall suction/injection on the linear stability of flat Stokes layers are investigated. A semi-analytical method is used to examine the stability of time-periodic boundary flows with wall suction/injection. Results show that the onset of instability of the flat Stokes layers can be suppressed by wall suction and enhanced by wall injection.
