| Abstract: | In this experiment,a large diameter pipe air-lift device was studied,and the clean water at room temperature was used as the fluid.The performance of the lift pipe with its internal diameter and length of 95 mm and 6 m was tested under various conditions.Through the analysis and process of the test data,the main flow pattern characteristics of the large diameter pipe lift device were studied and the feasibility of using the Golan flow boundary equation in the judgment of flow types in large pipes was verified.From the perspective of the gas water two-phase flow,the relationship among the gas equivalent velocity,the liquid equivalent velocity,the sliding velocity,the submerged ratio and the promote efficiency was comprehensively analyzed,And the variation pattern of the operating performance of the large diameter air-lift device was obtained.In the end,the reasonable value of the key performance parameters of the large pipe diameter air-lift device was proposed. |
