Often, and especially in canonical turbulence research, the belief is that initial conditions wash-out and the turbulence develops to a universal self-similar state [1, 2]. However, recent numerical work [3, 4] has shown that this hypothesis hold true only for some flows, and that the buoyancy driven (Rayleigh-Taylor) turbulence is dependent upon initial conditions, and a self-similar state has not been measured in experiments. Similarly, R-M flows, driven by a shock wave, have a time-dependent mixing evolution that is also dependent upon initial conditions [5, 6, 7, 8]. In this present study we focus on improving our understanding of the nature of initial conditions on R-M mixing.
