Rayleigh taylor instabilityとは
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 … See more • Java demonstration of the RT instability in fluids • Actual images and videos of RT fingers • Experiments on Rayleigh–Taylor instability at the University of Arizona • plasma Rayleigh–Taylor instability experiment at California Institute of Technology See more The inviscid two-dimensional Rayleigh–Taylor (RT) instability provides an excellent springboard into the mathematical study … 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 • Saffman–Taylor instability • Richtmyer–Meshkov instability • Kelvin–Helmholtz instability See more WebRésumé (eng) Rayleigh-Taylor instability under the effect of electromagnetic forces.
