Abstract

Liquid drops were released in laminar and transitional jet flows to investigate their deformation and breakup characteristics. Silicone oil and deionized water were the dispersed phase and continuous phase, respectively. Calibration experiments of oil drops rising in quiescent ambient water were performed to benchmark the experimental system and the image processing method. In jet flow, drop breakup probability, breakup time, and the characteristics of daughter drops were investigated in detail. To address the underlying mechanisms of the drop breakup, visualization experiments and two-dimensional particle image velocimetry (PIV) experiments of the single-phase jet flow were performed. Visualization experiments show that the jet flow changes from laminar to transitional in the Reynolds number interval between 1283 and 1610. Critical capillary and Weber numbers for drop breakup were estimated based on the mean flow velocity and mean deformation and were found to be of the order of 0.2 and 30 respectively for this particular flow system.
