Impinging jets

Summary: Large Eddy Simulation of supersonic jets impinging on a flat surface replicate the propulsion system of VTOL aircraft in hover. Our research focus is on understanding the turbulent fountain-flow generated underneath an aircraft and the intense sound produced from aeroacoustic resonance. Observations of the hydrodynamic and acoustic coupling of the two jets informs new models that provide insight and prediction of sound intensity over a range of impinging heights and propulsion configurations.
