A Row of Drops in a Quiescent Liquid

Abstract

Measurements are made of the effect of frequency of formation on the velocity of drops rising in a chain through quiescent liquids. The terminal velocity of drops of a given size rising in a quiescent liquid increases as the frequency with which they are formed at a nozzle increases. The variation of velocity of the drop with frequency of formation is considerably influenced by the eccentricity and the wake of drops.
Theoretical analyses are performed for motion and mass transfer of drops rising in a chain at high Reynolds number. The present analysis evaluates the minimum effect of frequency of formation on the velocity of drops and shows a trend similar to that of the experimental data.
