Sudden change of
flow conditions in a pipeline may cause the flow to become time dependent and
would start an undesirable physical phenomenon called water hammer. These
sudden changes can be caused by variety of scenarios and some of them include
valve operations (opening or closing), sudden power loss at pump stations and
load rejections or load acceptance at the turbines, etc. Because of its very
costly and sometimes deadly consequences, it is quite important that transient
scenarios be considered for pipe systems at design stage to ensure safety and
longevity of them. The present study is an attempt to develop a comprehensive
computer software that is capable of simulating, analyzing and solving most
commonly encountered fluid transient events. The code developed, titled as
H-Hammer, is already capable of using many boundary conditions to tackle a
large variety of problems involving fluid transients. Within the code, the
Method of Characteristics (MoC) are used to solve the basic unsteady pipe flow
equations. The code utilizes AutoCAD, Visual Basic 6.0 and MS Excel all
together for the purpose of analyses. The accuracy of the software was tested
by solving some existing problems offered in the textbooks written by those who
contributed significantly in the fluid transient area. Comparisons of the
results show that the results of the developed software is in good agreement
with the solutions given in those books.
