Biography

Hi, I’m Mikaya Parente. My project this summer focused on the acoustics of a non-axisymmetric supersonic jet, specifically examining an elliptic nozzle with a Mach 2 exit flow. While circular nozzles are widely studied, elliptic nozzles are far less understood—despite their potential applications in high-performance aircraft that produce hazardous noise levels exceeding 140 dB. Using the Hot Jet Facility at FCAAP, I collected far-field acoustic data by rotating the nozzle 360° and measuring sound intensity across various angles. Schlieren imaging and Scanning Stereoscopic Particle Image Velocimetry (S-SPIV) were used to visualize and quantify flow features, including shock cells and expansion fans. Preliminary results reveal inherently 3D acoustic behavior, with shock-related tones varying by axis orientation. These findings contribute to understanding complex jet noise mechanisms and pave the way for better noise prediction and reduction strategies in future propulsion systems.
