Fig. 20From: Compact higher-order gas-kinetic schemes with spectral-like resolution for compressible flow simulationsTwo-dimensional acoustic problem: radial distribution of the sound pressure △p obtained by 6th-order and 8th-order compact GKS at t=6 with 700×600 mesh points. The vortex center at t=6 is approximately located at (−3.9,0.0)Back to article page
