Data-Driven Multiobjective Optimization of Wave-Packets for Near-Field Subsonic Jet Noise

What is it about?

Aeroacoustics of innovative aircraft cannot disregard the development of low-order models for the jet noise source, which are essential to assess the propulsion-airframe interactions from the conceptual design stage. In this work, the near-field of a high-subsonic jet at a Mach number of 0.9 is represented as a cylindrical surface radiating the pressure disturbances of a wave--packet source, optimized using large-eddy simulation data from three lines at different radial distances.
