چکیده
Using the framework introduced by Rawley and Colonius [2] we construct a nonreflecting boundary condition for the one-way wave equation spatially discretized with a fourth order centered difference scheme. The boundary condition, which can be extended to arbitrary order accuracy, is shown to be well posed. Numerical simulations have been performed showing promising results.

Discretely Nonreflecting Boundary Conditionsfor Linear Hyperbolic Systems
Many compressible flow and aeroacoustic computations rely on accurate nonreflecting or radiation boundary conditions. When the equations and boundary conditions are discretized using a finite-difference scheme, the dispersive nature of the discretized equations can lead to spurious numerical reflections not seen in the continuous boundary value problem. Here we construct discretely nonreflectin...
متن کاملNonreflecting Boundary Conditions Based on Nonlinear Multidimensional Characteristics
Nonlinear characteristic boundary conditions based on multidimensional wave modeling are proposed for twoand three-dimensional full compressible Navier-Stokes equations with/without scalar transport equations. This model is consistent with the physics of flows and transport properties. Based on the theory of characteristics, the multidimensional flows can be decomposed into acoustic, entropy, a...
متن کاملNon-reflecting Boundary Conditions for Wave Propagation Problems
We consider two aspects of non-reflecting boundary conditions for wave propagation problems. First we evaluate a proposed Perfectly Matched Layer (PML) method for the simulation of advective acoustics. It is shown that the proposed PML becomes unstable for a certain combination of parameters. A stabilizing procedure is proposed and implemented. By numerical experiments the performance of the PM...
متن کاملFast and Accurate Computation of Time-Domain Acoustic Scattering Problems with Exact Nonreflecting Boundary Conditions
This paper is concerned with fast and accurate computation of exterior wave equations truncated via exact circular or spherical nonreflecting boundary conditions (NRBCs, which are known to be nonlocal in both time and space). We first derive analytic expressions for the underlying convolution kernels, which allow for a rapid and accurate evaluation of the convolution with O(Nt) operations over ...

Using the framework introduced by Rowley and Colonius [14] we construct a discretely non-reflecting boundary condition for the one-way wave equation spatially discretized with an explicit fourth order centered difference scheme. The boundary condition, which can be extended to arbitrary order accuracy, is shown to be GKSstable. We continue by deriving discretely non-reflecting boundary conditio...
