This paper presents an interface tracking method for modelling the flow of immiscible metallic liquids in mixing processes. The methodology can provide an insight into mixing processes for studying the fundamental morphology development mechanisms for immiscible interfaces. The VOF method employed here utilises the piecewise linear for interface construction scheme as well as the continuum surf...

We study numerically the simplest model of two incompressible, immiscible fluids shearing past one another. The fluids are two-dimensional, inviscid, irrotational, density matched, and separated by a sharp interface under a surface tension. The nonlinear growth and evolution of this interface is governed by only the competing effects of the Kelvin–Helmholtz instability and the dispersion due to...

Abstract We consider a model for the flow of two immiscible fluids in two‐dimensional thin strip varying width. This represents an idealization pore porous medium. The interface separating forms freely moving contact with wall and is driven by fluid surface tension. contact‐line incorporates Navier‐slip boundary conditions dynamic possibly hysteretic angle law. assume scale separation between t...

The linear Rayleigh–Taylor instability of two immiscible superposed non-Newtonian fluids saturated by a porous medium in the simultaneous presence interfacial surface tension and suspended dust particles is investigated. behavior described Jeffrey model. set coupled partial differential equations satisfying appropriate boundary conditions solved applying theory normal mode technique. exact solu...

Abstract We investigate thermal convection in two horizontal layers of miscible fluids with an initial state which the are at rest and temperature has a linear continuous vertical distribution, but concentration takes different constant values each layer. Because layered is not stationary state, most theoretical methods available for immiscible applicable to case. Here we propose new model flui...

We experimentally, numerically and theoretically investigate the nonlinear interaction between a cavitation bubble interface of two immiscible fluids (oil water) on multiple time scales. The underwater electric discharge method is utilized to generate near or at interface. Both dynamics short scale evolution much longer are recorded via high-speed photography. Two mechanisms found contribute fl...

In a recent experiment by Chung et al. [Nano Lett. 5, 1878 (2005)] and simulation by Stratford et al. [Science 309, 2198 (2005)] on immiscible blends containing nanoscale particles, it was shown that the phase separation of the two polymers can be prevented as a result of the aggregation of the nanoparticles at the interfaces between the two polymers. Motivated by these studies, we performed la...
