The Effect of Droplets Size on Drop-Drop and Drop-Interface Coalescence of Sunflower Oil in Water Emulsion

Abstract:
In this research work the effect of droplets size on drop-drop and drop-interface coalescence of sunflower oil in water emulsion in a non-uniform electric field has been in two systems “drop-drop and drop-interface coalescence” under ramp-ac and square-ac waveform types investigated. In this work, the process was operated with the utilization of a batch cylindrical separator under high voltage condition. In this experimental work were of a constant frequency
(60 Hz) and constant amplitude magnitudes 200 V/mm studied. Using a speed camera two patterns of coalescence for both drops-drops and drops-interface was observed: complete coalescence, incomplete coalescence. The middle size of droplets was observed between 200 and 650 micrometers using “Photron Fastcam viewer and image-pro software”.
