Research
Research has focused on the application of flow control to improving the performance of gas turbine compressors. Vortex generator jets have successfully been used to delay the onset of boundary layer separation on compressor blades at high incidence. This enables the design of highly loaded blades that allow increased pressure rise to be achieved by a single stage. The mechanisms by which both steady and unsteady actuators delay separation have also been studied and identified.
