Abstract Scope |
The penetration of a single bubble through the liquid-liquid interface is a quite common dynamic process in a wide range of industrial applications in metallurgical engineering. Generally, it entails mass transfer in multiphase (liquid-liquid) systems through the transport of the lower liquid to the upper phase, making liquid entrainment take place. The bubble penetration behaviours through immiscible liquids interface were discussed and the corresponding entrainment volume by different sized gas bubbles was also reported. The influences of bubble size and fluid physical properties i.e. density, viscosity and interfacial tension on both entrainment volume and film thickness on bubble surface were examined. I was fund that for the bubbles which can penetrate the interface directly and cause heavier liquid column, the entrainment volume of heavier liquid transported by rising bubbles decreases with increasing light liquid viscosity, heavy liquid viscosity and density, interfacial tension and decreasing bubble size. |
