Verification Case 4
PRODUCT: AFT Impulse 9
TITLE: ImpVerify4.imp
REFERENCE: Fluid Transients in Systems, 1993, Prentice-Hall, E. Benjamin Wylie, Victor L. Streeter, Page 195, Example 8-5
FLUID: Water
ASSUMPTIONS: Valve is described as “fast closing”. Closing profile is not specified. Impulse model assumes instantaneous closure.
RESULTS:
DISCUSSION:
This experiment was designed to cause transient cavitation, and the flow does cavitate. As is common with cavitation modeling the timing of pressure spikes is marginal, but the major features and magnitude of prominent spikes is represented.
