Single drop breakage was investigated in a lab-scale reciprocating plate column. A high-speed camera was used to capture the drop breakage process and drop interactions with the plate. Image processing was completed to collect information on breakage location, breakage probability, breakage time and number of daughter drops under different operating conditions. The flow structure near the reciprocating plate was calculated using a computational fluid dynamics simulation with a moving reference frame. Two breakage mechanisms were observed experimentally, those mainly due to shear stress and those due to plate wettability. Spatial and temporal analysis was completed for the numerical shear str..View full abstract
