Unevenly Mixed Two-Component Liquid and Its Flow Measurement

The flow structure of the unevenly mixed two-component liquid and its flow measurement The flow structure of the unevenly mixed two-component liquid is similar to the gas-liquid two-phase flow, however, due to the viscosity of the two phases at this time The properties, density, and tension at the two-phase interface are different from those of gas-liquid two-phase flow, so there are also certain differences in the flow structure. Fig. 3, shown in 96 is that by density is ' 〖'^! !!3 Various flow structures when oil and water are mixed and flowed in the vertical riser. With the increase of oil flow rate, the oil-water two-phase flow gradually changes from the fine bubble flow structure, elastic flow structure and massive flow structure shown in the figure to the mist flow structure. In the figure, the working medium of the fine bubble and elastic structure is oil, and in the mist flow structure, the working medium of the mist is water. Fig. 3, shown in 97 is the various flow structure representations of oil-water mixture in the horizontal pipe. When the water flow rate is large and the oil flow rate is small, the flow structure of oil and water is a fine bubble flow structure with fine bubbles located in the upper part of the pipe. When the water flow rate and the oil flow rate are both small, the flow structure of oil and water is a layered flow structure with oil above and water below. When the water flow and oil flow increase, the oil-water interface fluctuates, forming a wavy flow structure. When the water flow increases again, an elastic flow structure is formed. When the flow rates of water and oil are both large, oil and water form a mixed flow structure.
