Adaptive mesh refinement for computational aeroacoustics
Adaptive mesh refinement for computational aeroacoustics
An algorithm based on a block-structured adaptive mesh refinement (AMR) method is developed to solve computational aeroacoustics (CAA) problems with the aim of improving efficiency and providing an alternative to capture various, co-existing physics. A number of numerical issues associated with fine-coarse block interpolations, filter and damping techniques are addressed in order to employ high-order schemes under an
AMR environment. A number of benchmark problems including spinning modal radiation from an unflanged duct have been used to demonstrate the feasibility and efficiency of the approach. Initial results show promise.

Abstract
An algorithm based on a block-structured adaptive mesh refinement (AMR) method is developed to solve computational aeroacoustics (CAA) problems with the aim of improving efficiency and providing an alternative to capture various, co-existing physics. A number of numerical issues associated with fine-coarse block interpolations, filter and damping techniques are addressed in order to employ high-order schemes under an
AMR environment. A number of benchmark problems including spinning modal radiation from an unflanged duct have been used to demonstrate the feasibility and efficiency of the approach. Initial results show promise.
