LARGE CIRCULATING DROPS IN VERTICAL TUBES.

Abstract

Large drops falling or rising within vertical tubes containing other fluids are studied experimentally and theoretically. For an ideal nonresistive interface the roles of Bond number, Reynolds number, and a 'gravity-viscous number', along with density ratio and viscosity ratio, in determining the velocity, shape, and circulation of the drops are described. Dynamic theoretical relationships are derived and used to correlate available data. Discussions on the static shape and the critical Bond number are included for completeness. Many drop-fluid systems do not behave as if the interface were ideal. The buoyancy-driven drop within a vertical tube is suggested as a tractable physical system to study such interfaces. (Author)
