Investigation into the pressure-driven extension of the EPANET hydraulic simulation model for water distribution systems

摘要: Several hydraulic modelling approaches have been proposed previously to simulate pressure - deficient operating conditions in water distribution networks more realistically. EPANET-PDX is a pressure-driven extension of the EPANET 2 simulation model that has an embedded logistic nodal head-flow function. The analysis algorithm was investigated, improve its performance under extremely low pressure. By integrating line minimization procedure fully computational solution system equations, algorithm’s consistency improved by increasing efficiency examples considered demonstrated robust, computationally efficient, and applied frequently. Overall, results suggest reliable. formulation significantly faster than previous quality functionality preserved. For with satisfactory pressure, where direct comparisons were possible, consistently faster.
