Utilities rely on transient analysis of large pipe
networks to properly assess the potential level of
intrusion associated with negative pressure and its
effect on disinfectant residual efficiency. However,
the computational demand for large pipe networks
is significant, and computational effort and accuracy
of solution are interdependent.
This research analyzed the numerical accuracy of
solution and computational efficiency of two popular
methods, the method of characteristics (MOC)
and the wave characteristic method (WCM).
Results indicated that the WCM is a much more
efficient method for modeling transients, without
sacrificing accuracy. The WCM constitutes a feasible
tool that utilities can use to conduct essential
transient analysis and address serious low-pressure
transient problems and surge protection issues.
For water providers, transient modeling is a
"must do" item to safeguard drinking water quality
within their distribution systems. Now transient
modeling is also a "can do" task, using the efficient
and time-saving method described here. Includes 31 references, tables, figures.
