The Opposite of Good Vibrations - Evaluating FIV, AIV, FIP Guidelines from AFT Fathom and AFT Arrow
Learn how to use AFT Fathom and AFT Arrow to help calculate the Likelihood of Failure (LOF) for Flow Induced Vibration (FIV), Acoustic Induced Vibration (AIV), and Flow Induced Pulsation (FIP) in accordance with Energy Institute Guidelines to avoid v...
It's a Pump! It's a Turbine! It's a Pump as Turbine!
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 betwe...
What Is Transient Analysis?
You're tasked to perform a transient analysis of a piping system and it would be really helpful if there was a good software tool out there to help you. Well, you've come to the right place because AFT has great solutions! ...
Know Your Pump & System Curves - Part 3
In the final "Know Your Pump & System Curves" blog series, I am going to discuss the complexities behind pump vs. system curves for systems with pumps in series and parallel configurations. Multiple pumps in series configurations are relatively s...
Digital Twin – Identical or Fraternal?
When I was a child, I was jealous of twins. I thought how cool it would be to have a twin. I had twin cousins a few years older than I was that I saw on a frequent basis. I always got them confused. Which one was Roger, and which one was Ronny? A buz...
That Valve’s Got Character – Applying Pre-defined Characteristic Curves
Valves are often oversimplified during modeling. Understandably, defining a valve with its range of Cv at various open percentages requires much more information than an engineer may have during the initial design phase. However, just like handbook d...
When completing the analysis on a model, there is nothing more frustrating than having to do the same thing over and over again. Thankfully, using AFT's Piping Layout Wizard you will no longer need to rebuild your CAD, CAESAR II, and EPANET files to analyze the hydraulics using AFT Fathom, AFT Arrow, and AFT Impulse. In addition to GIS sh...
Establishing and maintaining an electrical grid is a monumental task spanning many professions and disciplines. Fluid dynamics plays an important role in nearly any method of power generation. Between ensuring safety, reliable production of power, and minimizing operational costs, there are countless ways that modeling fluid flow can offer improvements.
Here at Applied Flow Technology we like to make things easy for our end users. That is why AFT Products have been developed not only to give you accurate and reliable results but to save you time as well. Let's talk about the "Start Batch Run..." feature. What does this feature do? Let's imagine you have a model with many scenarios and you need to ...
I think this is the third monthly blog article I have written this year from an airplane over the Atlantic Ocean. Truly I do not save my monthly blogs for airplanes. I am really busy most all the time these days. Being on an international flight means having a long, forced time disconnected from the Internet and more free time than normal to write....
Seeing as this month is water month, we thought this would be a perfect time to highlight some of the great ways that AFT Fathom 10 can help with hydraulic analysis for water distribution, wastewater, and fire water systems. From building the model to exporting and presenting results, we offer several helpful features. We have heard our users...
An article published this month in the AWWA Opflow trade magazine relates that America has a trillion dollar problem with our municipal water distribution system due to pipe failures. This information is old news to the water industry. What is novel about this article is that it suggests the issue is largely caused by waterhammer (see Stop Costly W...
We've previously discussed how to make input data changes in AFT Models using the Excel Change Data feature on other blogs, but since we are continuously asked about expedited ways to input and change data, we've updated our feature to make things even easier. AFT Software has an abundance of features that make the model input process tremendously ...
