Separation flow control on a wall-mounted hump using pneumatically enhanced/deployed actuators

Research output: Contribution to conferencePaperpeer-review

Abstract

The performance of the pneumatically enhanced/deployed actuator (PEDA) separation control system is tested in this study. This hybrid flow control sytem comprises a deployable micro-vortex generator and a continuous steady blowing jet. The Glauert-Goldschmied wall-mounted hump, a well-studied geometry, is used to study the effect of the actuators in decreasing the size of the separation bubble that exists at the downstream end of the model. The flowfield measurement and interrogation techniques include wall static pressure measurements, particle image velocimetry, surface flow visualization and pressure-sensitive paint with helium tufting. The measurements validated the implementation of the PEDA system for separation control, with a maximum measured reduction of 60.3% in the size of the separation bubble.
