Vortex simulations of the Rayleigh-Taylor instability

چکیده
~ vortex t~chnique capable of calculating the Rayleigh-Taylor instability to large amplitudes in inviscid, mcompresstble, layered flows is introduced. The results show the formation of a steady-state bubble at large times, whose velocity is in agreement with the theory of BirkhotT and Carter. It is shown that the spike acceleration can exceed free fall, as suggested recently by MenikotT and Zemach. Results are also presented for instability at various Atwood ratios and for fluids having several layers.

Rayleigh–Taylor instability in nonlinear Schrödinger flow
The Rayleigh–Taylor instability (RTI) is a fundamental fluid instability that occurs when a light fluid is accelerated into a heavier one. While techniques for observing the RTI in classical fluids continue to improve, the instability has not been demonstrated in quantum fluids. Here, we exploit the formal equivalence between condensed matter and coherent nonlinear optics to observe the superfl...
متن کاملSingularity formation during Rayleigh-Taylor instability
During the motion of a fluid interface undergoing Rayleigh-Taylor instability, vorticity is generated on the interface baronclinically. This vorticity is then subject to Kelvin-Helmholtz instability. For the related problem of evolution of a nearly flat vortex sheet without density stratification (and with viscosity and surface tension neglected), Kelvin-Helmholtz instability has been shown to ...
متن کاملA Localized Approximation Method for Vortical Flows
An approximation method of Moore for Kelvin-Helmholtz instability is formulated as a general method for two-dimensional, incompressible, inviscid flows generated by a vortex sheet. In this method the nonlocal equations describing evolution of the sheet are approximated by a system of (local) differential equations. These equations are useful for predicting singularity formation on the sheet and...
متن کاملCritical torsional modes of convection in rotating fluid spheres at high Taylor numbers
A numerical study of the onset of convection in rotating, internally heated, selfgravitating fluid spheres is presented. The exploration of the stability of the conduction state versus the Taylor and the Prandtl numbers supplies a detailed idea of the laws that fulfil the four types of solutions obtained at low Prandtl numbers. The main result found is that axisymmetric (torsional) modes of con...
متن کاملOn the long time simulation of the Rayleigh–Taylor instability
We investigate the classical Rayleigh–Taylor instability with a phase-field method. Despite of the long history of numerical simulations for the Rayleigh–Taylor instability, almost all results were relatively short time experiments. This is partly because of the way of treating the pressure boundary conditions. We implement a time-dependent pressure boundary condition through a time-dependent d...
