title = "Flow and aero-optics around a turret. Part 1. Open loop flow control",
abstract = "A large percentage of the losses in performance and effectiveness of airborne optical systems are caused by turbulence. In particular, separated turbulent flow phenomena is present in several aero-optics applications. In an effort to reduce the adverse effects of turbulence in airborne optical systems, we are exploring the use of both open and closed-loop flow control over a cylindrical turret. A series of experiments were performed at Reynolds number of 2; 000; 000 that corresponds to a Mach number of 0:3 using a half scale test model. The 3D turret contained an actuation system that consists of 17 synthetic jets placed upstream from the leading edge of the aperture. Multiple actuation cases were tested to evaluate the effects of active flow control over the aperture area and their control authority. Simultaneous surface pressure and velocity measurements were acquired in the separated region for both with and without flow control. Pressure results from the open loop test presents reduction of 10 percent in the root-mean-square values when compare to the baseline case. Two-point statistics showed that the forcing is driving the flow towards homogeneity across the surface of turret.",
