基于有限体积法-有限元法的油水两相流超声衰减特性规律分析
Analysis of ultrasonic attenuation characteristics in oil-water two-phase flow based on FVM-FEM
摘要
Abstract
Oil-water two-phase flow in horizontal pipelines exhibits complex and diverse dynamics,with intricate fluid structures and uncertain mechanisms of flow regime transitions.To facilitate the visualization of the oil-water two-phase flow process,a multiphase flow ultrasonic testing simulation platform was established to study the complex interfacial effects and relative motion between phases.Utilizing finite volume method(FVM)based three-dimensional fluid simulation software,a dynamic flow model for oil-water mixed inputs was developed.By extracting the coordinates of the multiphase interface cross-section,a two-dimensional geometric partition model of the test field was constructed using finite element method(FEM)within a multiphysics coupled simulation software,establishing a coupled FVM-FEM visualization simulation platform for multiphase flow.The mechanisms of interaction between oil-water two-phase flow and ultrasound were investigated under ultrasonic excitation.The research findings indicated that in the dynamic water-in-oil and oil-in-water flow regimes within the horizontal pipeline,the number of discrete phases increased within a certain range,but decreased due to coalescence,with the ultrasonic attenuation coefficient positively correlating with the number of discrete oil or water droplets.An in-depth exploration of the transition process from water-in-oil to oil-in-water reverse regimes was conducted,where both phases existed in a non-discrete form and the ultrasonic attenuation coefficient increased with the number of layers.关键词
