Description

ABSTRACT The purpose of the present work is to investigate the detailed structure of the induced flow generated by discharge plasma actuators, particularly the turbulent characteristics, and demonstrate how these can be leveraged in the control of laminar and turbulent flow fields. This will be accomplished by performing detailed measurements of the flow field structure, both locally and globally, around actuators with varying geometries. Input parameters will include actuator geometry, material properties (both electrode and dielectric), and voltage amplitude, frequency, and waveform shape. The end goal will be to verify the analytical models and optimize the actuator output. Development and application of novel actuator geometries, namely to enhance flow control by generation of crossstream structures, will also be investigated, including the examination of annular arrangements to use as replacements for synthetic jet actuators.
