Acoustic propagation on irrotational mean flows using time-domain finite and infinite elements
A formulation is presented for the computation of transient wave fields propagating on unbounded, irrotational mean flows. The numerical scheme is based on an inner mesh of conventional finite elements, which is matched to high-order multipole infinite elements in the far field. The scheme is validated against simple transient test solutions and shown to be effective for large three-dimensional problems provided that iterative solvers are used to advance the solution at each time step.

Abstract

A formulation is presented for the computation of transient wave fields propagating on unbounded, irrotational mean flows. The numerical scheme is based on an inner mesh of conventional finite elements, which is matched to high-order multipole infinite elements in the far field. The scheme is validated against simple transient test solutions and shown to be effective for large three-dimensional problems provided that iterative solvers are used to advance the solution at each time step.
