TLDR
In this paper, an experimental study of the stability of the interface of two gases traversed by ash-wave was conducted and it was found that the interface is unstable both in the case of shock wave passage from the lighter to the heavier gas and for passage in the opposite direction.Abstract:
Results are presented of an experimental study of the stability of the interface of two gases traversed by ashockwave. It is found that the interface is unstable both in the case of shock wave passage from the lighter to the heavier gas and for passage in the opposite direction. The interface disturbance grows linearly with time in the first approximation.read more

The Instability of Liquid Surfaces when Accelerated in a Direction Perpendicular to their Planes. I
TL;DR: In this article, it was shown that when two superposed fluids of different densities are accelerated in a direction perpendicular to their interface, this surface is stable or unstable according to whether the acceleration is directed from the heavier to the lighter fluid or vice versa.
Nonuniformities in Shock-tube Flow Due to Unsteady-boundary-layer Action
Harold Mirels,Willis H. Braun +1 more
TL;DR: In this article, the boundary layer along the walls of a shock tube is evaluated, which induces pressure and velocity gradients within the core of potential flow, and the authors present an evaluation of the boundary.

Dynamic Instability of Accelerated Fluids
TL;DR: In this article, it was shown that the asymmetrical growth of an interface separating two fluids of different densities, under the influence of an imposed acceleration (Rayleigh-Taylor instability), is mainly a nonlinear phenomenon.
