Dynamics mode results for the H1 example simulation

View the results

1. Open the Pressure trend.

2. Open the Pressure Profile plot.

3. Run the Close Outlet Valve Scenario.

The following figure shows the results in the Pressure trend.

These results show that the pressure response after AVEVA Process Simulation closes the outlet valve very closely resembles the theoretical and experimentally validated response proposed by Contractor1.

The simulation time step (dt) and the number of segments in the pipe (PIP1.N) are important in the calculation of the water hammer. These values appear on the flowsheet above the pipe and you change them by directly modifying the values on the flowsheet.

The following figure shows the results in the Pressure Profile plot. The plot shows the pressure wave as it travels through the pipe segments. Note that the wave is visible only while the Close Outlet Valve Scenario is running.
