This paper describes a novel numerical algorithm for simulating interfacial dynamics of non-Newtonian fluids. The interface between two immiscible fluids is treated as a thin mixing layer across which physical properties vary steeply but continuously. The property and evolution of the interfacial layer is governed by a phase-field variable / that obeys a(More)
In this note we examine the implications of Cahn-Hilliard diffusion on mass conservation when using a phase-field model for simulating two-phase flows. Even though the phase-field variable φ is conserved globally, a drop shrinks spontaneously while φ shifts from its expected values in the bulk phases. Those changes are found to be proportional to the(More)
