Steady Motion of a Drop along a Liquid Interface
نویسندگان
چکیده
We investigate the motion of a liquid drop as it flows along the interface of a liquid film. Steady, two-dimensional solutions are found in the lubrication limit for a horizontal and inclined plane. The effects of the physical parameters on the interface shapes are studied. When the plane is inclined, solutions are found only for a special set of parameter values.

A Numerical Study of Drop Motion in Poiseuille Flow
The cross-stream migration of a deformable drop in two-dimensional Poiseuille flow at finite Reynolds numbers is studied numerically. In the limit of a small Reynolds number (<1), the motion of the drop depends strongly on the ratio of the viscosity of the drop fluid to the viscosity of the suspending fluid. For a viscosity ratio 0.125, the drop moves toward the centre of the channe while for t...

متن کاملEffect of Nondimensional Parameters On the Internal Circulation of a Liquid Drop Moving with the Surrounding Gas
The internal flow circulation dynamics of a liquid drop moving in a co- or counter-flowing gas stream has been numerically studied. The present work is concerned with the time accurate numerical solution of the two phase flow field at the low Mach number limit with an appropriate volume tracking method to capture motion and deformation of a liquid drop. It is shown that relative velocity betwee...

متن کاملAn experimental study of transient effects in the breakup of viscous drops
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-tensiondriven motion which occurs after the flow is stopped abruptly. For modest extensions, drop breakup does not occur with the flow on, but may occur following cessation of the flow as a result of deterministic motions associated with intern...
