低含液管线内液膜厚度分布特性的试验研究
Experimental Study of Liquid Film Thickness Characteristics in Gas Pipeline with Low Liquid Loading
摘要
Abstract
The gas-liquid flow with low liquid loading appeared in wet gas gathering pipelines.Experimental pipeline was established according to similarity criteria.A system of measuring transient liquid film thickness was designed with micrometer.Film distribution characteristics in the gas pipeline with low liquid loading were studied.The results show fluctuation in the film distribution.Liquid film is concentrated on the bottom of horizontal pipe.Thin film exists on the side walls of horizontal pipes.Under the same superficial gas velocity,the region occupied by liquid film is extended and the value of thickest film is increased first and then decreased with increasing superficial liquid velocity.Under the same superficial liquid velocity,the thickest and thinnest values of film thickness are decreased,and the circumferential equivalent uniform film thickness is decreased with increasing superficial gas velocity in the vertical pipe downstream of the elbow.关键词
