Simulation-Based Analysis of the Near Field in a Supersonic Jet Controlled by Plasma Actuators


Summary: The near field of a Mach 1.3 jet is analyzed under the influence of m = 0 and m = 1 excitation at St = 0.3, 1.0, and 2.0. The analysis, which includes azimuthal mode decomposition of the pressure field, shows that at higher frequencies, the large structure formation is inhibited and peak SPL amplitudes diminish, in a manner that is generally consistent with experimental results.
