Abstract

An experimental study has been performed to investigate the wake of a three-dimensional turret with an aspect ratio of 1.17 at a diameter based Reynolds number of 5:5 × 105. This work was performed to develop a better understanding of both the spatial structure and time dependent nature of the wake with and without suction based active flow control. For the current tests, active flow control was applied around the leading edge of the turret aperture to match a control configuration that might be used for mitigating aero-optic distortions. Stereoscopic PIV was used to evaluate the spatial structure of the wake and dynamic surface pressure measurements were used to study the time dependent behavior. The results of this work have shown that the turret flow field is complex and highly three dimensional when considering both the spatial and temporal nature of the wake. With the application of active flow control, both the spatial structure and time dependent behavior of the wake were signficantly altered.
