Abstract

Abstract — In general the severity of transient associated
with water hammer depends upon the rate of change of the
flow conditions, for example the rate of valve closure or
opening determines for any pipeline the magnitude of the
resulting transient. A well understood analysis of transient
propagation may allow potentially suppression transients.
However, this is not always possible for the range of reasons
and in this case it may be necessary to incorporate surge
control or suppression devices. In this paper, detailed study
of three different valve types of commonly used are included
to determine the best functional valve. In this computational
investigation, method of characteristics has been
implemented with appropriate B.C. to study the effect of
using different valves. The three different valve types have
been investigated subjected to a different closing time. It has
been found that the globe valve is the proper valve to be
used at slow closure process while butterfly valve is better in
fast closure process in the view of minimizing the water
hammer peak pressure.
