Abstract
We review our experiences with absorbing layer boundary conditions in fluid flow. The absorbing layer is constructed by splitting the temporal derivative and applying independent damping in each split equation. This methodology follows the basic principle outlined by Berenger for the solution of Maxwell’s equations and is known as the Perfectly Matched Layer (PML) boundary condition. We consider several physical problems and numerical algorithms. The results indicate that the PML boundary condition efficiently minimize reflections and are suitable for aeroacoustic computations.
