It's a Pump! It's a Turbine! It's a Pump as Turbine!

Model Pumps as Turbines

Pumps and turbines may serve opposite purposes, but fundamentally, they operate under the same principles. Both pieces of equipment convert between usable work and fluid energy, and both often use an impeller to make the conversion. Differences between the two pieces of equipment quickly start to appear as they are examined with more detail. A pump...

Get in Control with Control Valves

Having some trouble getting your modelling under control? This blog will discuss some tips on how to properly use a control valve in AFT Fathom and how to interpret some common control valve warnings. For simplicity this blog will primarily discuss control valves in the context of AFT Fathom. However, the concepts discussed in this blog also apply ...

Find Help Faster with the Documentation Portal

AFT strives to make our interface intuitive and user-friendly, but we know that pipe flow modeling can be complex. That's why the AFT team have worked to put together the AFT documentation portal, a new centralized place to find all of our help resources for AFT Fathom, AFT Arrow, AFT Impulse, and AFT xStream. Here's a quick summary of what you can...

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 transient cavitation

The term transient 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 pipes and pipe system components, but how to predict and calculate transient cavitation is not something that is as equally understood. In...
