Averaging under Rayleigh-Taylor instability and density mushy region generation

European Journal of Mechanics - B/Fluids. 2019. Vol. 74. P. 152-158.

A stratified liquid with two layers separated by a fast oscillating interface in the case of Raleigh--Taylor instability
is considered. The averaged equations are derived, and it is shown that a mushy region of a certain density appears after averaging. The similarity between this fact and the case of unstable jump decay is discussed.
