EFFECT OF REYNOLDS NUMBER ON COALESCENCE OF DROPLETS IN CREEPING FLOW THROUGH A TUBE

摘要

The coalescence of droplets in creeping flow through a tube was experimentally examined. The coalescence time of two droplets and the diameter of the clearance area between the droplets were measured. The experimentally measured coalescence times were compared with those determined by semi-theoretical formulas and generally good agreement was observed between the two. The effect of the Reynolds number of the creeping flow on the coalescence of the droplets was also investigated.
