Research Abstract

The objective of the study was to develop the computational approach to solve the aerodynamic sound through fluid and solid boundaries. The target was the aerodynamic sound from aircrafts and automobiles, thus the Cartesian-based approach was used to treat the complicated geometries as well as the sound propagation precisely. The Cartesian-based approach coupled with Immersed Boundary Method proved its usefulness through the CFD-CAA coupled simulation of fan noise from a jet engine. The further study is required to establish the new unified method to compute aerodynamic sound through fluid and solid boundaries effectively.
