چکیده [English] | ||
In order to investigate the effects of drop size and its falling distance on dropinterface coalescence time, the so-called coalescence cell had been designed and built. The selected chemical materials were as follows: Water-Toluene, Waternormal Heptane and 60% aqueous Glycerol- Toluene. In all experiments, the oil phase was as continuous phase. Before each run, the two immiscible phases were mutually saturated by mixing and then, separated from each other. It was indicated that, the increasing of drop diameter or drop falling distance increases dropinterface coalescence time, separately. These factors also cause the subsidence of multistep coalescence phenomena in water- Toluene system, which has usually occurred severely. Added to these, the vertical or horizontal fluctuations of drop on interface, causes the delaytion of drop coalescence. | ||
