Turbomachinery Fluid Mechanics and Control

Abstract

Slot jet flow control concepts were developed and explored for the application to axial compressor stators. The concepts were demonstrated in a high speed wind tunnel to simulate a highly loaded stator passage. The midspan boundary layer flow could be forced to attach most effectively with addition of streamwise vorticity (vortex generators and discrete jets) however the endwalls continue to be poorly behaved until large fractions of the overall flow were passed through the slot jet.
