WebThe Rayleigh-Taylor instability, or RT instability (after Lord Rayleigh and G. I. Taylor), occurs any time a dense, heavy fluid is being accelerated by light fluid. This is the case with a cloud and shock system, or when a fluid of a certain density floats above a fluid of lesser density, such as dense oil floating above water. WebApr 29, 2024 · Dry-granular material flowing on rough inclines can experience a self-induced Rayleigh-Taylor (RT) instability followed by the spontaneous emergence of convection cells. For this to happen, particles are different in size and density; the larger particles are denser but still segregate toward the surface. When the flow is initially made of two layers …

WebJan 23, 2024 · The classical Rayleigh–Taylor instability occurs when a heavy fluid overlies a lighter one, and the two fluids are separated by a horizontal interface. The configuration is unstable, and a small perturbation to the interface grows with time. Here, we consider such an arrangement for planar flow, but in a porous medium governed by Darcy’s law. First, … WebThe Rayleigh-Taylor instability (RTI) causes small bumps or perturbations on the sphere or interface of the capsule to grow, exponentially fast. [2] ... ICF scientists must be aware of the time scales of the RT instability in their capsule design and make sure that the fusion is faster than the hydrodynamic instability. Otherwise, ...
