... has been studied by many researchers. The analytical one-dimensional frequency domain wave theory has a great advantage of providing accurate results without the additional computational cost related to the modern time domain simulation models. For assessing the validity of analytical and numerical...

... to the mean discharge, Q 0 . Unsteady flow in a piping system is described by the continuity and momentum equations. These equations in the time domain are converted into the frequency domain by assuming a sinusoidal variation of pressure and flow and by linearizing the nonlinear functions...
