Abstract

Aerodynamic noise from a cone in a uniform flow is computed using the Ffowcs Williams-Hawkings (FW-H) equation. The time accurate flow data is obtained using a finite volume flow solver on an unstructured grid. The FW-H equation is solved for surface integrals over a permeable surface away from the cone. Predictions from the FW-H code are compared with direct calculations by the flow solver at a few observer locations inside the computational domain. A very good qualitative match is obtained. Sound directivity patterns in the azimuthal and in the longitudinal directions are presented. The FW-H code is also validated against a model problem of a monopole in a uniform mean flow.
