3 High-accuracy schemes have been proposed here to solve computational acoustics 4 and DNS problems. This is made possible for spatial discretization by optimizing 5 explicit and compact differencing procedures that minimize numerical error in the 6 spectral plane. While zero-diffusion nine point explicit scheme has been proposed 7 for the interior,… (More)
