“…We therefore use a simple coalescence model based on a specified thickness of the film: the two interfaces are merged if their separation is less than one grid spacing. This criterion is similar to that used for impinging molten metal drops (21) . Our criterion makes the results quite similar to what is seen when using the level set method (22) or the volume of fluid method (23) .…”

The formation and breakup of an axisymmetric immiscible, viscous, laminar compound jet flowing vertically downward into and breaking up in another immiscible liquid is studied numerically. We use a front-tracking/finite difference method to track the unsteady motion and the breakup of the compound jet interfaces, which are governed by the incompressible Navier-Stokes equations for Newtonian fluids. We consider the formation and breakup of a three-fluid compound jet in which the inner fluid density is greater than the shell's fluid density, and compare with the case when the inner fluid density is less than the shell's fluid density. The effects of interfacial tensions in terms of Weber number and interfacial tension ratio are investigated. An increase in Weber number leads to an increase in the breakup length of the compound jet and a decrease in the size of compound drops.

“…Thus the no-slip boundary conditions at the surface of the nozzle are implicitly satisfied. This technique has already been applied to the problem of molten metal solidification (Che et al, 2004). One of the advantages of this technique is that the geometry of the nozzle can be changed without rebuilding the grid structure, and thus the numerical code remains simple.…”
