LOW-PRESSURE CONCERNS?
WHY THEY SHOULD BE A HIGH PRIORITY.

The majority of engineers don't worry themselves
with the low pressures of waterhammer. 

For instance, an upsurge in pressure inevitably leads to a downsurge. Or, a pump trip could drive a low-pressure wave through your system. If these pressures are low enough, your liquid can vaporize, which is unpleasant.
We call this transient cavitation. See how AFT Impulse
​​​​​can avoid 
potentially catastrophic waterhammer events caused by low pressure.

HOW DOES AFT IMPULSE
MODEL CAVITATION?

Transient cavitation is not a common system consideration. Even if engineers
know they should examine it, they don't know
how to account for it. AFT Impulse resolves
this problem. Let us do the math while you
do the analysis.

A PROPOSED GUIDELINE FOR APPLYING WATERHAMMER PREDICTIONS UNDER TRANSIENT CAVITATION CONDITIONS

There are few resources on transient cavitation modeling, as there are too many considerations to make it a simple task. AFT's founder, Trey Walters, tackled the problem of how to predict pressures while transient cavitation is present. Review the paper he presented at the 2018
PVP conference.

When there are so many demands for your attention
in the office, it can be hard to focus on Zoom and Teams trainings. This is why AFT offers in-person training seminars. Whether you're new or experienced, you'll
find AFT seminars a worthwhile investment of your time.

System Modeling Seminar: 

  • Understand surge communication times
  • Modeling transient cavitation
  • Model pump transients, including​​​​​​inertial effects
  • Modeling time & event based transients
  • Model relief & vacuum breaker valves
  • Troubleshoot AFT Impulse models
  • Predict unbalanced pipe forces
  • Choosing the best trade-offs between model run times
  • Model pipe sectioning round off errors
  • Understand graph & animation features

UPCOMING WEBINAR
Gas Accumulators in AFT Impulse 
Wednesday, July 6, 2022
10:00 AM - 11:00 AM (MDT)


Do you model or size gas accumulators?
You may have gotten a glimpse at these in a
previous AFT webinar. This webinar will dive
a bit deeper to explain uses of the updated Gas Accumulator junction in AFT Impulse.
We will also discuss the assumptions the
Gas Accumulator makes and how the
Gas Accumulator can be used to model
a closed tank.
