High-order Non-reflecting Boundary Conditions for the Linearized 2-D Euler Equations: No Mean Flow Case.

摘要

Higdon-type non-reflecting boundary conditions (NRBCs) are developed for the 2-D linearized Euler equations with Coriolis forces. This implementation is applied to a simplified form of the equations, with the NRBCs applied to all four sides of the domain. We demonstrate the validity of the NRBCs to high order. We close with a list of areas for further research.
