Abstract
Numerical Simulation of two-phase flow in pipelines is an important tool to predict the behavior of the flow quantities, especially in the real-life engineering problems. A one dimensional single-pressure four-equation model was used in previous works to simulate specific types of flows, such as transient stratified-pattern two-phase flows in gas pipelines, with or without a PIG passing through the pipeline, and in the occurrence of a leakage in the system. The model is discretized within a finite-difference framework and is solved using the Flux-Corrected Transport (FCT) method, where the eigenstructure stays within the hyperbolic region. This work uses the common test case of gravity dominated flow, also known as the water faucet problem, to promote further testing of the numerical method and the single-pressure four-equation model in question. We chose this test case as benchmark in this work because it offers an analytical solution and the particular presence of a discontinuity in the volume fraction before reaching the steady state.
