Mechanism for the breaking of symmetry of the directions of the velocity shear in the Rayleigh-Taylor instability
Bazdenkov S. V. , Pogutse O. P.
A few-parameter model (similar to the Lorentz model) is proposed for describing the generation of shear flow in a plasma or liquid as a result of the onset of the Rayleigh-Taylor instability. The sign asymmetry of the velocity shear in the flow which is generated and also the sign asymmetry of the electric field in the plasma are explained on the basis of this model.
