Abstract

Perfectly Matched Layer (PML) boundary conditions are derived in generalized curvilinear coordinates for three-dimensional aeroacoustic applications. The resulting governing equations are solved numerically, formulated in 4th/6th order compact finite differences. The PML equations are programmed in a subroutine, which is easily incorporated to the main program LINEULER (Linearized Euler's equation solver). Two and the three-dimensional benchmarks problems are solved to investigate the efficiency and accuracy of the PML boundary conditions. Extensive investigation on the PML parameters has been conducted to determine the optimum combination of parameters used in the computations.
