Abstract

Direct Numerical Simulation results of aeolian tones generated by a two-dimensional obstacle (square cylinder and NACA0012 airfoil) in a uniform flow are presented and the generation and propagation mechanisms of the sound are discussed. The two-dimensional unsteady compressible Navier-Stokes equations are solved by a highly-accurate finite difference scheme over the entire region from near to far fields. Results show that sound pressure waves are generated in response to vortex shedding. In both cases of square cylinder and NACA0012 airfoil, the generation and propagation mechanisms are affected by the angle of attack.
