内容記述 | An experimental study is reported on the turbulence structure of a two-dimensional (2-D) two-phase gas-liquid flow. A test cannel, in which a nearly 2-D, uniform two-phase air-water flow occurs, was used. This channel was a vertical, narrow gap space made up of two large concentric pipes. Measurements of turbulent diffusivity of the liquid phase were made for bubbly flows and churn flows in this channel. Namely, a solution of dye stuff was introduced at a constant rate from a fixed line source into a fully developed uniform two-phase flow in the channel. Flow at the downstream locations was recorded by a video camera, and roughly one thousand pictures of the flow were analyzed to obtain the distribution of dye stuff concentration using image processing. From this distribution, the turbulent diffusivity was determined. As for bubbly flow, a model for the turbulent diffusivity is proposed and examined. | |||||
