Abstract: | |
Elbow is often used in pipeline transportation, fluid flow velocity and pressure change dramatically when passing through the elbow, therefore the elbow influences the efficiency of pipeline transportation. In this paper, the model of oil-water two-phase flow is established by using FLUENT software. Having Simulated the different initial velocity fluid through elbows of different curvature-diameter ratio, the changes of velocity and pressure were obtained and the secondary motion was imitated. The change regulation of the pressure gradient and velocity along with the curvature-diameter ratio are summarized. It has certain reference value for the design and further studies of the 90 degree elbow. |
