    Numerical Analysis of the Impact of the Interior Nozzle Geometry on Low Mach Number Jet Acoustics

    The flow and acoustic fields of subsonic turbulent hot jets exhausting from three divergent nozzles at a Mach number M=0.12 based on the nozzle exit velocity are conducted using a hybrid CFD-CAA method. The flow ...
