Quasi-Steady Flow in Hydraulic Systems Using MOC

Abstract

The Method of Characteristics (MOC) is utilized effectively in many industries to calculate hydraulic transients in almost all pipeline systems. Recently it has been suggested as a suitable calculation procedure for long term (extended time) quasi-steady flow problems. It might serve as an alternative approach to using rigid water-column (lumped inertia) calculations, or to integrating over time with a series of steady state calculations, which are two procedures receiving recent attention. This paper provides a unique approach within the MOC framework, by modifying terms in the pipeline partial differential equations. When carried through the MOC it leads to a minor modification in a transient code by introducing the two new parameters. The method is developed and applied to a network example herein.Copyright © 2000 by ASME
