Rigid or deformable bodies moving through continuously stratified layers or across sharp
interfaces are involved in a wide variety of geophysical and engineering applications, with …

A computer-controlled four-roll mill is used to examine two transient modes of deformation of
a liquid drop: elongation in a steady flow and interfacial-tension-driven motion which occurs …

In this paper we examine some general features of the time-dependent dynamics of drop
deformation and breakup at low Reynolds numbers. The first aspect of our study is a …

A computational technique for solving fluid problems with free surfaces and interfaces is
presented. The conventional cell volume fraction approach is employed for tracking the …

Theoretical and computational aspects of the method of interfacial dynamics for flow at
vanishing Reynolds number are considered. The mathematical formulation relies on the …

Electrostatic jetting from a free liquid surface offers an alternative to conventional
electrospinning in which jets are emitted from spinnerets. In this work we analyze a system …

Microencapsulation of cells as a means of insulin or other protein delivery (for example, for
gene therapy) has not yet realized its potential. Three aspects of this problem are illustrated …

The cree** flow of a liquid film along an inclined periodic wall of arbitrary geometry is
considered. The problem is formulated using the boundary-integral method for Stokes flow …

The dynamics of isolated air bubbles crossing the horizontal interface separating two
Newtonian immiscible liquids initially at rest are studied both experimentally and …

A rigid object moving in a viscous fluid and in close proximity to an elastic wall experiences
self-generated elastohydrodynamic interactions. This has been the subject of intense …
