Query: Scrambled and Unscrambled Turbulence   The linked fluid dynamics videos depict Rayleigh-Taylor turbulence when
driven by a complex acceleration profile involving two stages of acceleration
interspersed with a stage of stabilizing deceleration. Rayleigh-Taylor (RT)
instability occurs at the interface separating two fluids of different
densities, when the lighter fluid is accelerated in to the heavier fluid. The
turbulent mixing arising from the development of the miscible RT instability is
of key importance in the design of Inertial Confinement Fusion capsules, and to
the understanding of astrophysical events, such as Type Ia supernovae. By
driving this flow with an accel-decel-accel profile, we have investigated how
structures in RT turbulence are affected by a sudden change in the direction of
the acceleration first from destabilizing acceleration to deceleration, and
followed by a restoration of the unstable acceleration. By studying turbulence
under such highly non-equilibrium conditions, we hope to develop an
understanding of the response and recovery of self-similar turbulence to sudden
changes in the driving acceleration.
