Thermal Control and Oxygen Transfer Using Mist and Circulation Flow Generated By A Rotating Cone

Abstract
We have experimentally found the liquid film flow characteristics risingalong the outer surface of a rotating cone. When the film flow goes upfully upward, the liquid film cannot keep the film wise condition and iseventually atomized into a mist flow. In this research, the effect ofmist using the rotating cone on both oxygen transfer and the surroundingthermal environment is investigated. The oxygen transfer performance isevaluated by using the volumetric mass transfer coefficient and oxygentransfer rate when the ambient temperature of gas phase is changed by amist flow using a rotating cone. Experimental results show that thedesired gas phase temperature can be maintained and the oxygen transferis simultaneously promoted by controlling the quantity of the mist.Namely, it is found that both the oxygen transfer enhancement and thedesired thermal control of the ambient gas phase can be achieved onlycontrolling the rotating speed of the cone.
