Manga, M. (1996) Dynamics of drops in cavity flows: Aggregation of
high viscosity ratio drops, Physics of Fluids, vol. 8,
The interactions of
deformable drops in cavity
flows is studied numerically in the limit of low Reynolds numbers for a
two-dimensional model. Flow in a square cavity is driven by the steady
motion of one of the walls.
Deformable drops will migrate across streamlines until they
reach an equilibrium trajectory or equilibrium position; the rate
and direction of migration
depend on both the viscosity ratio and capillary number.
High viscosity ratio deformable
drops have a tendency to aggregate and form clusters.
The presence of a deformable dispersed
phase results in an elastic behaviour of the suspension.
