  The dynamics of drop(s) has been simulated by the finite volume/moving mesh
interface tracking method (MMIT) with adaptive mesh refining and coarsening. In
MMIT, the interface is of zero thickness and moves in a Lagrangian fashion. A
number of mesh refining and mesh coarsening schemes have been developed to
distribute the mesh in an optimized way to achieve computing efficiency and
accuracy. Three cases are displayed in this video, which include a droplet pair
in tandem impulsively accelerated by a gaseous flow, a droplet moving through a
convergent-divergent liquid-filled tube, and a droplet moving toward a sloped
solid wall. The fluid dynamics videos of the simulations are to be presented in
the Gallery of Fluid Motion, 2011.
