Sound generation by flow over a two-dimensional cavity

A study calculated sound generated by flow over a cavity at a Mach number of 0.1 and a Reynolds number based on cavity length of 5,000. The cavity flowfield is found to oscillate quite regularly at the Strouhal number of 0.58, which produces an acoustic source of the same frequency.
