smontosp / Ffowcs-Williams-and-Hawkings-Equations

Open source codes/programs of acoustic analogies to calculate subsonic and supersonic noise characteristics induced by unsteady flow, moving geometry and mutual interactions either in a stationary or a moving medium. A permeable interface with arbitrary mesh is adopted to enclose the nonlinear region calculated by unsteady CFD solvers (Fluent).
