AFT Blog

Welcome to the Applied Flow Technology Blog where you will find the latest news and training on how to use AFT Fathom, AFT Arrow, AFT Impulse, AFT xStream and other AFT software products.

To Affinity and Beyond!

Pump manufacturers often supply performance curves at a specified speed. While this is useful when the pump only runs at that rated speed, performance changes when the pump has a Variable Frequency Drive (VFD). A VFD changes the shaft speed, which, in turn, changes the performance curves. If the manufacturer only supplied a curve at a sin...

How does AFT Impulse model cavitation?

The term cavitation is thrown around frequently when talking about the effects that transient events have on piping systems. It is widely and correctly understood to be something that can be harmful to pumps and pipes, but how to predict and calculate cavitation is not something that is as equally understood. In this blog, we will dive in...
