Two-dimensional acoustic problem: sound pressure contours obtained by 6th-order and 8th-order compact GKS at t=6 with 700×600 mesh points. Shock and vortex Mach numbers are Ms=1.2 and Mv=1. Here 150 equal-spaced sound pressure contours from − 0.5 to 0.05 are plotted. The dash line represents rarefaction region, and the solid line represents the compression region
