WebMar 19, 2024 · When a more dense fluid overlies a less dense miscible fluid, the resulting instability is named a Rayleigh–Taylor instability [1, 2].This situation can arise in a large number of physical problems, for example within stars [], the atmosphere [], the oceans [] and even beneath the Earth’s crust [].A useful overview of the Rayleigh–Taylor instability was … 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 fluid. Examples include the behavior of water suspended above oil in the gravity of Earth, mushroom clouds like those from volcanic eruptions and atmospheric nuclear e…
