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...
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...
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 ...
When building a model in any of AFT's software all pipe and junction numbers must be unique. These pipe and junction numbers can be useful for sorting information in areas such as "Model Data" and "Output". Therefore, keeping an organized structure for these pipe and junction numbers is strongly advised. Though, like every project, unforeseen devel...
I don't have any tips for decluttering your garage or office desk, but I can offer you a tip on how to declutter your natural gas model. Perhaps it will save you some time as well in the design phase. As engineers, we like details and will enter as many as possible into our models. I've seen several AFT Arrow and xStream models with natural gas mix...
Last week in Tucson, Arizona I attended the annual meeting of the Hydraulic Institute – the largest association of pump manufacturers in North America. There I heard about the latest updates on the fluid handling industry. Then I went on my first tour of a wastewater treatment plant and learned about how they use 2500-year-old pump techno...
