The Development of a Simulation Model of
Pipeline Network Systems with Check Valve
Tianhe We
The objective of this thesis is to design and implement a software package to rnodel and simulate pipeline network systens with check valves. The application package is written under the window's environment to provide the hydraulic engineer a user friendly interface for case of simulation and analysis without requiring to write code.
Discussion of the phenomenon of hydraulic transients, derivation of the differential equations, comparison of different kinds of analysis methods, and investigation of the method of characteristics solution and basic boundary conditions are ai1 established. The check vdve dynamic equation is investigated for the analysis of pipeline transients, and formulate for flow torque acting on the valve discs are derived by introducing the orifice sequence model.
Dynamic behavior of pumps is considered during the pipeline transients, and the analysis of this behavior combines the method of characteristics with check valve dynarnics, pump characteristic and pump boundary conditions both for pump failure and pump start up. Numericd solutions to pipeline transients, check vaive dynamicq and pump characteristic are established. Finally, the implementation into a working simulation program of a dynamic model for pipeline network systerns with check valves is described, and a user guide for the software HyrioAmlps and HyrioGruphic is presented
