Description
Summary:Accurate and rapid prediction of the pipeline water hammer process is beneficial to the design and operation of the pipeline system. This paper proposed an accurate and efficient wave tracking method (EWTM) for the numerical simulation of water hammer in pipeline system. The proposed EWTM was developed based on the unsteady friction model and a new implementation scheme, which is combined with the Lagrangian scheme and the Eulerian scheme. The wave propagation equations of reservoir, valve and discrete vapor cavity model (DVCM) were also derived. To evaluate the performance of the EWTM, the single-phase water hammer and the two-phase water hammer were calculated with the EWTM and compared with the method of characteristic (MOC) and the experimental data. The evaluation result shows that EWTM has the same calculation accuracy as MOC, and the proposed EWTM method is over 90% more efficient than the MOC, which addresses the accuracy and efficiency limitations of the conventional wave tracking method (WTM).This paper provides a new idea on the improvement of simulation procedures and efficiency, which can be used for rapid calculation of transient flow in complex pipelines and for fault diagnosis which requires the highest numerical simulation accuracy.
