Evolution of length scales and statistics of Richtmyer-Meshkov instability from direct numerical simulations.

Turbence statistics, i.e., the probability density functions of the velocity and its longitudinal and transverse derivatives, show a self-similar decay and thus that turbulence evolving from RMI is not fundamentally different from isotropic turbulence, though nominally being only isotropics and homogeneous in the transverse directions.
