EXPERIMENT OF HIGH GAS-LIQUID FLOW IN STRAIGHT VERTICAL PIPE CARRYING LIQUID

In pipe flow visualization experiments in the rack,compressed air and spray liquid are used as test media, with liquid in acontinuous simulation and testing of experimental parameters; high-speedvideo camera is used to capture the actual shape of the droplet gasstream --- ellipsoid. It was found that:that sphere model and elliptical sphere model give, respectively,a deviation of 10\% and 58.3\% compared with experiment.This paper analyzes the stress state in ellipsoid and the experimental dataare used to build a new mathematical ellipsoid model, and the newmodel gives results in agreement with water production line of seven wells.In40 plexiglass tube rack visualization the self-development of high 16m, experiment, using compressed air and water as the experimental medium (gas-liquid ratio "10000), to simulate different pressure, gas and other gas well under the conditions of carrying a continuous fluid, high-speed High-speed video cameras to capture the actual flow in the droplet shape --- similar to the sphere ellipsoid, test wellhead pressure, temperature, gas and other parameters. It was found that Turner spherical model calculated and experimental results deviation of 10%, spe70016 ellipsoid model and the experimental results deviation of 58.3%. Article analyzes the ellipsoid stress state, the application of experimental data fitting drag coefficient has been derived, consistent with the experimental wells to bring the new ellipsoid fluid mathematical model. This paper selects seven western Sichuan gas field production data, for example with water wells, according to derived ellipsoid model of the new formula, the results in line with the production wells. The experimental research for the research and teaching and guiding both the importance of field applications.
