Sound Radiated from Turbulent Flow over Two and Three-Dimensional Surface Discontinuities
… field sound from two-dimensional forward facing steps, gaps with rounded corners and swept forward facing steps with rounded corners were made. The sound from a forward facing step is shown to exhibit effects of non-compactness. Rounding the step corner results in consistent drop in sound levels …
