On the vorticity-generated sound for moving surfaces

A formulation for analyzing the mechanism of vorticity-generated sound is presented, which is based upon an extension of a boundary integral equation method for unsteady quasi-potential compressible flows. The extension is obtained through an exact decomposition of the velocity field into potential...
