From: Time-Resolved Measurements of Turbulent Mixing in Shock-Driven Variable-Density Flows
An illustrative temporal evolution of merging between two vortices [X and Y in (a)], and the associated scalar evolution shown in snapshots 67 μs apart, starting at 5.550 ms after incident shock in (a), 5.617 ms in (b), 5.684 ms in (c), 5.751 ms in (d), 5.818 ms in (e), 5.885 ms in (f), 5.952 ms in (g), 6.019 ms in (h) and 5.086 ms in (i). The vectors are velocities in the frame of reference of vortex-X (same scale as Fig. 4, in m/s) in (a) and line-contours represent vorticity with same levels as Fig. 8 (in s−1). See Supplementary video S4 for the evolution at full temporal resolution.
