Phase-field model for the Rayleigh–Taylor instability of immiscible fluids

The Rayleigh–Taylor instability of two immiscible fluids in the limit of small Atwood numbers is studied by means of a phase-field description. In this method the sharp fluid interface is replaced by a thin, yet finite, transition layer where the interfacial forces vary smoothly. This is achieved by introducing an order parameter (the phase field) whose variation is continuous across the interf...

Message Passing Fluids: Molecules as Processes in Parallel Computational Fluids

In this paper we present the concept of MPF, Message Passing Fluid, an abstract fluid where the molecules move by mean of the informations that they exchange each other, on the basis of rules and methods of a generalized Cellular Automaton. The model is intended for its simulation by mean of message passing libraries on the field of parallel computing. We present a critical analysis of the nece...

Rayleigh–Taylor instability in cylindrical geometry with compressible fluids

A linear stability analysis of the Rayleigh–Taylor instability RTI between two ideal inviscid immiscible compressible fluids in cylindrical geometry is performed. Three-dimensional 3D cylindrical as well as two-dimensional 2D axisymmetric and circular unperturbed interfaces are considered and compared to the Cartesian cases with planar interface. Focuses are on the effects of compressibility, g...
