چکیده
Solving aero-acoustic or electromagnetic wave-dominated problems often requires finding accurate infinite domain solutions on a finite computational domain. One way of accomplishing this is to formulate absorbing boundary conditions through the technique of perfectly matched layers (PML). We discuss recent developments of PML methods for the absorption of acoustic waves in homogeneous mean flows and address the prospects of extending existing results to more general scenarios, including inhomogeneous and, possibly, fully non-linear flows.
