Abstract
Nowadays transporting oil in water annular flow is one of the more advanced methods of pipeline transportation, but the stability of water annulus is an important prerequisite for the good operation of the pipeline transport. Therefore, the influence of valve on the stability annular flow of high-viscosity oil and water is discussed, based on the technique of sliding mesh, and tracked the oil–water interface by VOF method, the flow characteristics of the oil and water core-annular flow (CAF) are calculated by the finite volume analysis software under different opening speed of valve and the thickness of water annulus. Finally, the simulation result has been proved by CAF experiments. The results show that the numerical calculation will help to predict the flowing rate of oil and water CAF inside the valve and the downstream pipeline. During the time that the ball valve is working, the flow course of oil and water CAF is divided into three stages, among which are the breakage of annular flow, the development of annular flow and the stabilization of annular flow. The turbulent flow after valve gradually decreased at the valve opening of 50%. The opening speed of ball valve has a great influence on the pressure and velocity of the flow field after the ball valve, and the velocity at the inlet and outlet of ball valve reaches a maximum. At the same time, the opening speed has little effect on the valve flow resistance coefficient. Only by increasing the water annulus thickness could promote oil–water CAF to be generated quickly when the valve is from the closed to fully opened. The conclusion could provide technical support for the application of oil–water core-annular flow.
