Publication Summary
Dispersion-relation-preserving (DRP) spatial differentiation schemes are investigated for staggered non-uniform finite-volume grid type. It is shown that the staggering improves the numerical accuracy and stability whether the grid is uniform or non-uniform. The effect of the non-uniformity in the grid on the optimization procedure of the schemes is discussed. The spatial differentiation schemes are tested for the aeroacoustic problems of monopole and quadrupole radiation, showing the effectiveness of the non-uniform grid and the optimized high-order scheme.
