Experimental study of the shape and motion of flattened drops in a Hele-Shaw Cell
> The motion and shape of a flattened drop and bubble through another continuous liquidphase (conveying phase) are investigated experimentally, using a narrow gap HeleShaw cell. Seven different liquid-liquid systems were tested. In all cases the continuousphase was the more viscous wetting phase. A number of observations on the shape andmotion of the elongated flattened drops are noted and discussed. In the capillaritydominated (Ca<1.69×10-6) region, the irregular shape of the discontinuous phasedrops changed with time and position, and the drop velocity was much lower than thatof the conveying phase. Three different shapes of stabilized elongated drops wereobserved at higher Capillary numbers. The conditions that lead to the appearance ofstabilized elongated drops are discussed. The velocities of these stabilized elongatedflattened drops were 2 to 4.7 times higher than that of the conveying liquid. Acorrelation to predict the elongated flattened drop shape as a function of thedimensionless parameters governing the system is developed based on the experimentalresults.
