Abstract: An effective numerical method is presented to compute transients in piping systems in which frequency-dependent parameters influence the response. Frequency-dependent friction is utilized as the ...

Abstract: The classic formula for waterhammer wavespeed is extended to calculate the complex-valued, frequency-dependent wavespeed in a viscoelastic pipe, which takes into account the effect of viscoelasticity ...

Abstract: The nature of hydraulic transients in rock‐bored tunnels is expected to be frequency‐dependent. Three issues related to the frequency dependence are addressed in this paper. A complex‐valued and frequency‐dependent wave ...

Abstract: The randomness of transient events, and the variability of its associated dependencies, ensures that water hammer and surges in a pressurized pipe system are inherently stochastic. To improve reliability-based structural ...
