Abstract

Abstract

An oil-gas pulse flushing method was proposed to remove contaminants in the pipe by changing the charging time to generate a pulse oscillating flow. The oil-gas pulse dynamic model and the mathematical governing equation were established, user defined function (UDF) secondary development based on Ansys Fluent module and simulation test were carried out. k−ε two equation turbulence model and volume of fluid (VOF) model for gas-liquid two-phase flow were used, and Simple algorithm was carried to solve iteratively, the effects of radial velocity, turbulence intensity and dynamic pressure on z = 0 cross-section at different positions from the inlet, as well as wall shear force were studied. The results show that the flow velocity, turbulence intensity, dynamic pressure and wall shear force of oil-gas two-phase flushing are higher than that of single oil flushing. Pulse flushing compresses air to act on oil in the form of pulse, which enhances turbulence pulsation and increases inertia shear stress. The cleaning effect is better than continuous charging method. The result can provide theoretical basis and engineering practice method for pipeline oil-gas pulse flushing.
