Separation Control Using ZNMF Devices: Flow Physics and Scaling Laws

Abstract

The primary goal of this research is to implement a closed-loop control system to control separated flow and to evaluate the performance of the controller. A control system that includes an array of actuators, sensors (pressure sensors or lift/drag balance) and a digital controller is proposed to control flow separation in a closed-loop fashion. The first chapter introduces the flow physics and active control approaches of flow separation. It is organized as follows. First, a brief overview of separation control is provided to orient the reader, followed by the motivation. Than a technical background section is presented to review previous work reported in the literature. Finally, the objectives and technical approaches of this research are presented.
