Progress and prospective of computational aeroacoustics

Abstract

The origin and research category of Computational Aeroacoustics (CAA) are introduced firstly. The early progress and applications are summarized, focusing on the two key elements of CAA, high accuracy spatial and time discretization schemes and non-reflecting boundary conditions. Furthermore, the research advances of CAA in the past five years are highlighted, including nonlinear non-reflecting boundary condition, non-uniform time integration method, space discretization method applicable for complex geometry and broadband time domain impedance boundary condition. Finally, the future prospective of CAA is presented briefly.
