ProLB - Simulation of circular cavity noise

Simulation of circular cavity noise, with an aspect ratio height over diameter of one,
at M=0.2 and Re=470 000. Noise emissions are generated by a turbulent
boundary layer development into a shear layer, which impinges the leading edge of
the cavity, eventually generating a complex recirculation and an aeroacoustic feedback.
