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. WebAn interesting possibility in which matter accretes onto the star via the magnetic Rayleigh-Taylor (RT) instability has been investigated in the theoretical studies by e.g., [6–8]. More recently, the global three-dimensional (3D) magnetohydrodynamic (MHD) simulations by e.g. [9–11] have shown

WebOct 1, 1996 · Turbulent mixing due to the Rayleigh-Taylor instability is experimentally found to vary strongly with the temporal acceleration profile g(t).For constant g, the bubble amplitude h b increases as gt 2 consistent with previous results. For sustained acceleration profiles with dg/dt≠0, h b increases, not with the displacement Z=∫∫g dt′dt, but with the …
