Bringing your AFT Fathom model into AFT Impulse, or building a new model in AFT Impulse allows potential worst case scenarios to be analyzed efficiently for transient events. Waterhammer caused by events such as sudden pump trips, valve closures, and pump startups can add serious strain to the system due to high pressures, cavitation, and vibrational damage.
Multiple cavitation models are available in AFT Impulse to help engineers calculate pressures in the system from the collapse of vapor cavities. Forces in the system can also be calculated by AFT Impulse and exported to be analyzed using pipe stress software.
AFT Impulse helps engineers create multiple scenarios to model and compare different surge suppression devices for the system such as relief valves, accumulators, vacuum breaker valves, etc, or to test different operational changes to reduce or eliminate the damage caused by these occurrences.
