Computational Considerations for the Simulation of Shock-Induced Sound
Jay Casper,Mark H. Carpenter +1 more
TL;DR: The extent to which a high-order accurate shock-capturing method can be relied upon for aeroacoustics applications that involve the interaction of shocks with other waves has not been previously quantified and is initiated in this work.
Finite-volume implementation of high-order essentially nonoscillatory schemes in two dimensions
TL;DR: In this paper, high-order Runge-Kutta methods are employed for time integration, thus making these schemes best suited for unsteady problems, and numerical results suggest that these schemes converge according to the higher-order spatial accuracy.

Computing unsteady shock waves for aeroacoustic applications
TL;DR: In this paper, the authors investigated the effect of stencil biasing parameters and numerical flux formulas on the magnitude of the spurious entropy wave, which contributes significantly to noise generation in supersonic jet flows, and the level of numerical error introduced in the calculation was defined as a function of shock pressure ratio, shock speed, Courant number, and mesh density.

Using high-order accurate essentially nonoscillatory schemes for aeroacoustic applications
Jay Casper,Kristine R. Meadows +1 more
TL;DR: In this article, a modification of previously developed stencil-biasing procedures is proposed, which allows a freer adaptation near discontinuities without disturbing the biased, stable stencils that are desired in smooth regions.
