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...
We recently discussed the new features coming out in AFT Fathom 13 and AFT Impulse 10. Now let's talk about the compressible gas and steam side of the product launches. You may be more familiar with AFT Fathom, as it is our flagship incompressible steady state analysis product. AFT Arrow is its counterpart for compressible steady st...
We've been working hard to bring users a wide range of functions from more intuitive menus and interfaces to new ways to present model data. In total, there are more than 25 new features and enhancements that will be released in the coming months. While all four of our primary products will be released very closely together, below is the list for A...
September 14. That is the day I consider to be AFT's official birthday. In 1993 I resigned from my job in the power industry and started working on AFT Fathom 1.0 full-time that day. Thirty years ago today I was assembling a business plan and figuring out how I could finance the founding of AFT. I have found myself reflecting a lot this year – on A...
I suspect Europeans who live near world history sites just accept this as normal. For a backwater American like me, it is amazing to come across the final resting places of Isaac Newton and Galileo. I recently had that privilege in London and Florence. On my 60th birthday in early April, I had the privilege of visiting Westminster Abbey. Among the ...
We are excited to share Workspace Layers, a new feature for the Applied Flow Technology software suite that you'll be working with soon! A group of layers is like a stack of transparencies. Each layer displays specific, customizable information and together they combine to form the Workspace view for your model. This is concept is much like Adobe P...
In April I became old. I mean really, really old. I might even be called ancient. But not as ancient as the Romans. You see, in April I had my 60th birthday. The day fell a week short of a twice-delayed waterhammer conference held in The Netherlands. When my wife asked me what I wanted to do for my 60th birthday, I responded "Since we will already ...
Last month I presented a technical paper that was both the easiest and the hardest paper I have written. The paper was on a waterhammer accident in 2016 at an alumina refinery which caused a slurry pump to catastrophically fail. The pump casing exploded and the hot, caustic slurry it was pumping sprayed onto a technician nearby resulting in severe ...
