Simulation of Surge Reduction Systems Using Dimensionally Reduced Models

Abstract

The focus of this paper is to study transient flow processes in a trunk oil pipeline initiated by a sudden stoppage of a pumping station equipped with an overpressure protection system. Our analysis is based on a dimensionally reduced model, in which a one-dimensional (1D) system of partial differential equations (PDEs) is used to simulate flow in the pipeline. The pumping units, valves, and overpressure protection systems are modeled by algebraic systems of equations and ordinary differential equations (ODEs) in zero-dimensional (0D) models. Our numerical results demonstrate the efficiency of overpressure protection systems. In addition, the numerical results are compared with field measurements.
