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, … See more The evolution of the RTI follows four main stages. In the first stage, the perturbation amplitudes are small when compared to their wavelengths, the equations of motion can be linearized, resulting in exponential instability growth. In … See more The analysis in the previous section breaks down when the amplitude of the perturbation is large. The growth then becomes non-linear as the spikes and bubbles of the instability tangle and roll up into vortices. Then, as in the figure, numerical simulation of … See more The inviscid two-dimensional Rayleigh–Taylor (RT) instability provides an excellent springboard into the mathematical study of stability because of the simple nature of … 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 … See more • Saffman–Taylor instability • Richtmyer–Meshkov instability • Kelvin–Helmholtz instability See more • Java demonstration of the RT instability in fluids • Actual images and videos of RT fingers See more WebJun 6, 2024 · Rayleigh-Taylor instability.
