Acoustics and vibrations in a complex piping network with pump startup–shutdown transients

Pump dynamic operational conditions result in extreme transient events that can enhance the response of piping networks. The predominant transients during rapid startup and shutdown are mainly studied for centrifugal pumps scarce reciprocating pumps. Our study extends conventional steady-state analysis to include effect pump loading on pulsatile flow-induced acoustics vibrations a complex network. forced resulting from acoustical–structural coupling is assessed by utilising one-dimensional multiphysics acoustic model beam structural model. network responses flows (rapid start-up-shutdown events) compared due loading. With startup–shutdowns operations accompanied flows, combination characteristics plane waves vibrations. excites fundamental, low-frequency eigenmode causes pipeline similar reservoir–pipe–valve (RPV) systems.
