Schematic shock-interface diagram depicting progression of events in the laser-driven experiments without energy deposition. Crossing locations are approximate.
visualization for resolution 3D data from Ref. 1 along with present simulations with energy deposition. The blue surface is a density isosurface, reflecting the approximate location of the Be tube interface. For reference, the second shock enters the mixing layer (“reshock”) at t = 10 ns and exits the mixing layer at t = 17 ns.
Volumetrically integrated TKE and mixing from Ref. 1 , with no added energy; for reference, initially nonperturbed, and perturbed material interfaces were also considered.
CDFs of the vorticity magnitude from Ref. 1 , with no added energy. Sampling regions are indicated within red lines on distributions of vorticity magnitude ω. The DNS data is from Jiménez et al.. 20 The simulated data was filtered based on vorticity content by setting for , with the vorticity magnitude threshold chosen such that . Comparison with the DNS data suggests reaches a value close to 100 for the 2.5 μm resolution data.
(a) Mixing width measure for the simulation without energy deposition and the simulations with energy deposition. (b) Asymptotic outer-scale for the simulation without energy deposition and the simulation with energy deposited at 12 ns.
and . For reference, the second shock enters the mixing layer (“reshock”) at t = 10 ns and exits the mixing layer at t = 17 ns.
