From: Time-Resolved Measurements of Turbulent Mixing in Shock-Driven Variable-Density Flows

Evolution of vorticity (ω in s−1) at three different times corresponding to (a) late-time pre-reshock (T1 = 4.9 ms), (b) early time post-reshock (T2 = 5.3 ms) and (c) late time post-reshock (T3 = 7.5 ms). Velocity vectors are scaled to 1% of magnitude in (a) and to 10% in (b) and (c). See Supplementary video S2 for the full evolution in W3.
