Abstract:The conventional transfer matrix models of fluid elements were modified and a convenient method of dealing with junction boundary conditions was introduced. A large-scale fluid network was modeled by standard procedures, and a network was expressed with characteristic matrix and boundary condition matrix. By simple operation of matrix, the dynamic characteristics of a large-scale fluid network was simulated in frequency domain. Validation test on a large-scale pipeline network showed that the proposed method is accurate and practical.
Key words: hydraulic network model; hydraulic simulation; transfer matrix; large-scale system
