Active and Passive Flow Control of a High Reynolds Number Axisymmetric Jet

Master's Thesis


The focus of this study is to employ active and passive control devices into an axisymmetric jet in order to enhance mixing and eventually control noise. The active control device used in this study is plasma actuators, while the passive control device is a set of delta tabs. Several investigations have discussed ways of controlling the flow in order to enhance mixing by using tabs and other similar devices. An overview of the theory of plasma generation will be discussed, along with the plasma actuator construction for this project. The goal is to implement these flow control devices to perturb the flow structure dynamics, which is believed to be the source of noise production. A description of the flow facility will be provided with the required specifications it renders for this project. Information available for the base case with the nozzle extension in this facility will be presented before the use of implementing a flow control device. The second objective is to create a data base that can be used for future work in this field.
