Daniel Bodony: Aeroacoustic predictions in complex geometries

Historically, algorithms developed for computational aeroacoustics focused on the accurate treatment of wave propagation in geometrically simple domains. The move towards more predictions involving complex geometries has been somewhat slower. In this talk we will discuss recent advancements made in high-fidelity aeroacoustic prediction methods for complex geometries using the overset mesh (or Chimera) approach. Focus will be given to proving energy stability in overset techniques and in a novel approach to handling moving Chimera meshes distributed over many processors. Examples of the algorithms will be given including the prediction and control of jet noise and high-fidelity simulations of rotor- stator wake interactions.
