水平突变管内油水两相流数值模拟
The Numerical Simulation of Oil-Water Two-Phase Flow in Horizontal Mutation Pipe
摘要
Abstract
Using the VOF model of computational fluid dynamics to simulate oil-water two-phase flow in horizontal sudden expansion pipe and contractible pipe,the crude oil in the two-phase flow is medium viscous oil and the moisture content is high, ranging from 50% to 80%.The results show that:the different water content flow in oil-water two-phase flow in the sudden expansion pipe and sudden contraction pipe belong to oil-in-water stream,the pressure fluctuation in diameter mutation changes obviously,but the pressure change trend is affected little when the moisture content changes from 50% to 80%.Flow in the mutant diameter pipes with different water content of oil-water two-phase flow pattern obtained can provide certain reference when involving mixed oil-water two-phase flow transportation problems in crude oil pipeline.关键词
