Waterhammer Analysis of Oil Transportation Pipeline Using Brunone-Vitkovsky Unsteady Flow Friction Model

A transient flow model for heated oil transportation pipeline is built with application of continuity, momentum and energy conservation equations of pipe flow. The transient friction term of the model incorporates both of the steady and unsteady friction and the Brunone-Vitkovsky model is selected to compute unsteady flow friction in pipeline. The method of characteristic, finite-difference scheme and Newton-Raphson method are utilized to solve the model and the computer simulation software is developed on the base of investigation. Ultimately, the hydraulic transient behavior along a heated oil transportation pipeline in the condition of an interim pump station stoppage is simulated. The results show consider the unsteady flow friction is useful to improve the accuracy of water hammer simulation.
