Rayleigh–taylor rt instability
WebThe Rayleigh–Taylor instability, or RT instability , is an instability of an interface between two fluids of different densities which occurs when the lighter fluid is pushing the heavier fluid.[2][3][4] Examples include the behavior of water suspended above oil in the gravity of Earth,[3] mushroom clouds like those from volcanic eruptions and atmospheric nuclear … WebWe present an application of the Variational Average-Atom in Quantum Plasmas (VAAQP) model and numerical code to dense plasmas radiative properties. We propose an approximate Detailed Configuration Accounting (DCA) approach starting from the variational model of configurations in jellium.
