ShockView from LDi is a highly accurate water-hammer and shock wave modelling system. Water hammer is a dynamic phenomenon, and LDi's preventative hardware also operates on dynamic principles, so ShockView is based on many partial differential equations. The software can be used for two purposes:
To do this, you will need to know the following system parameters accurately:
Bulk modulus of material
Inlet steady state pressure
Mass flow rate
Maximum allowable pressure
Valve closing or pump start-up time
Valve area change characteristic e.g. linear
From this information, ShockView produces a graph showing how the pressure within the pipe varies over time after the valve is closed.
ShockView has been tested extensively by comparing its predictions with results from an actual test rig. The results of these tests show how accurate ShockView is.

If you have a pipeline or pump user problem which requires pulsation analysis, diagnostics, or prediction by software:
The definitions of many problems can be found at Liquid-Dynamics.com.
Liquid Dynamics provides pipeline and pump user problem analysis, diagnostics, and prediction by software. For water hammer and shock solutions pulsation dampening and shock alleviating devices can be obtained from our associate websites PulseGuard and ShockGuard.
