WebBased on a bootstrap instability method, we prove the existence of unstable strong solutions in the sense of L 1-norm to an abstract Rayleigh–Taylor (RT) problem arising … The Rayleigh–Taylor instability, or RT instability (after Lord Rayleigh and G. I. Taylor), ... (assuming other variables such as surface tension and viscosity are negligible here). The difference in the fluid densities divided by their sum is defined as the Atwood number, A. See more The Rayleigh–Taylor instability, or RT instability (after Lord Rayleigh and G. I. Taylor), is an instability of an interface between two fluids of different densities which occurs when the lighter fluid is pushing the heavier … See more The RT instability can be seen as the result of baroclinic torque created by the misalignment of the pressure and density gradients at the perturbed interface, as described by the two … See more The analysis in the previous section breaks down when the amplitude of the perturbation is large.
