InfoSurge Pro is a surge engine that can simulate transient events caused by turbine operation,
00:11
and pressure reducing valve (PRV) or flow control valve (FCV) responses to hydraulic transients, or pressure surges.
00:22
In water applications, these surges are also known as water hammer.
00:28
Pressure extremes usually occur during a period of transient flow and may exceed design limits of system components.
00:37
Put simply, surge events can be extremely damaging if the system is not adequately protected, making surge analysis critical.
00:46
Transient flow simulation and analysis is an essential requirement for assuring the safety
00:53
and safe operation of water distribution piping systems.
00:58
InfoSurge rapidly and accurately computes pressures and flows throughout the piping system
01:04
during transient operation and evaluates alternate operational scenarios and surge protection schemes.
01:12
Transients in water distribution systems are a major concern for pipeline analysis, design, and operation,
01:21
as they have the potential to wreck or damage pipeline systems and equipment, induce adverse water quality conditions,
01:29
reduce system efficiency, and threaten the integrity and quality of supply as well as public safety.
01:37
These impulse loads normally develop when the steady state velocity is suddenly altered
01:43
following rapid valve closure or opening, vapor pocket collapse, safety valve blow down, and starting or stopping of a centrifugal pump.
01:54
The magnitude of the pressure changes is proportional to the change in flow velocity.
01:60
These events typically happen within milliseconds but may span several seconds in larger systems.
02:07
Pressure surges developed during startup and shutdown,
02:10
and/or under accident conditions such as loss of power to the pumps or inadvertent valve closure, can easily exceed steady state values.
02:20
Cavitation or excessive pressure surging during transient operation can lead to pipeline or component failure.
02:28
Surge control devices are often required to prevent the development of such conditions.
02:35
The proper selection and evaluation of these devices requires a reliable transient flow analysis.
02:42
To the engineer, transient analysis of the performance of piping systems
02:47
is often more important than the analysis of the steady state operating conditions used as the design basis.
