PRODUCT: AFT Impulse 9

TITLE: ImpVerify17.imp

REFERENCE: Watters, G.Z., Modern Analysis and Control of Unsteady Flow in Pipelines, Ann Arbor Science Publishers Inc. pp. 170-173, Example 7-1

FLUID: Water

ASSUMPTIONS: Transient cavitation turned off

RESULTS:

DISCUSSION:

Column separation would occur after 5.19 seconds and Watter's model did not account for this so he stopped his model at this point. AFT Impulse can model column separation, but for the purposes of this verification the cavitation capabilities are turned off in the AFT Impulse model. This will result in the warning saying system pressure has gone below vapor pressure.
