WebMay 13, 2024 · But in supersonic flows, there are two changes; the velocity and the density. The equation: - (M^2) * dV / V = drho / rho tells us that for M > 1, the change in density is much greater than the change in velocity. To conserve both mass and momentum in a supersonic flow, the velocity increases and the density decreases as the area is increased. WebHere, we follow [57] to set up high and low-density jets at Mach 800 and Mach 100, respectively. In each case, the domain is set as Ω = [0, 1 / 2] × [0, 3 / 2], with outflow conditions on the top and right sides, a reflecting condition on the left, and mixed inflow / outflow conditions on the bottom to introduce the jet.
