Abstract

In this study, unsteady incompressible flow field and aerodynamically generated noise of 2D and 3D cavity flows are investigated. In the case of 2D flow fields, standard k-ϵ, standard k-ω and SST k-ω is used and in the 3D case, flow field is computed using standard k-ω turbulence model. All numerical results are compared and validated with experimental measurement for Low Reynolds and Mach numbers. All unsteady flow fields results are used to compute a cavity noise using Ffowcs William - Hawking (FW-H) Acoustics Analogy. In the case of 3D cavity, the effect of quadrapole terms on the aerodynamically generated noise is investigated defining permeable interior surface.
