Characterization of Receptivity in Jet Flow Control
Abstract
This report describes a combined experimental and computational investigation of the receptivity of incompressible and compressible jets to acoustic and fluidic perturbations. Receptivity is the mechanism by which external disturbances transfer energy to instabilities in the flow. The focus of this research is characterizing jet receptivity for a broad range of actuator and flow parameters. The numerical computations explore the influence of forcing amplitude, combined harmonic and steady blowing, actuator location, Mach number, and temperature ratio. Experimental investigations compare the effectiveness of various types of actuators and document the flow response to high amplitude forcing by a periodic fluidic actuator.
