Describe the importance of surge analysis when designing a water distribution system.
InfoSurge Pro is a surge engine that can simulate transient events caused by turbine operation, and pressure reducing valve (PRV) or flow control valve (FCV) responses to hydraulic transients, or pressure surges.
In water applications, these surges are also known as water hammer.
Pressure extremes usually occur during a period of transient flow and may exceed design limits of system components.
Surge events can be extremely damaging if the system is not adequately protected, making surge analysis critical.
Transient flow simulation and analysis is an essential requirement for assuring the safety and safe operation of water distribution piping systems.
InfoSurge rapidly and accurately computes pressures and flows throughout the piping system during transient operation
InfoSurge evaluates alternate operational scenarios and surge protection schemes.
Major concern for pipeline analysis, design, and operation.
Have potential to:
Normally develop when steady state velocity is suddenly altered following:
Magnitude of pressure changes is proportional to change in flow velocity.
Events typically happen within milliseconds but may span several seconds in larger systems.
Pressure surges developed during startup and shutdown, and/or under accident conditions—such as loss of power to the pumps or inadvertent valve closure—can easily exceed steady state values.
Cavitation or excessive pressure surging during transient operation can lead to pipeline or component failure.
Surge control devices are often required to prevent development of such conditions.
Proper selection and evaluation of devices requires a reliable transient flow analysis.
To the engineer, transient analysis of the performance of piping systems is often more important than the analysis of the steady state operating conditions used as the design basis.
