Title: A Mach 1.92 jet and its near acoustic field
A round Mach 1.92 jet is simulated with high-order finite differences and fourth-order Runge-Kutta time advancement. The turbulence is visualized with contours of vorticity magnitude and the radiating sound field with contours of dilatation (divergence of velocity).
