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...
It is always interesting to see items in the news where our software has played a role. Last week a breakthrough in nuclear research was achieved at Lawrence Livermore National Laboratory's (LLNL) National Ignition Facility (NIF).
You have just finished designing your system and built a model of your system in AFT Fathom and have convinced your team and the client that the system will achieve all the desired pressures, flow rates, and temperatures. The next big question is, “How much will this system cost?” With AFT Fathom, you have the ability to answer that question in great detail! You can easily determine the full cost of pipe materials and system components! Not only that, but you can quickly figure out how much it will cost to install and operate the entire system! You will even be...
There are two good reasons you should care that Applied Flow Technology is celebrating it's 20th anniversary this year.
One of the many new features in AFT Impulse is the ability to show junction locations in profile plots. This can be enormously helpful when analyzing large, complicated systems. When enabled, all junction locations are identified by a vertical bar with a junction ID flag at the top. To show junction locations, click on the button in the toolbar.Show Junction Locations will also work for animations.
AFT Impulse 5 was released today and offers a plethora of new features sure to keep waterhammer engineers more productive than ever - and help them build even safer piping systems. How did AFT Impulse get to where it is today?
Applied Flow Technology is proud to release a new version of AFT Impulse, now at version 5. AFT Impulse 5 encapsulates all of the new interface and navigational enhancements from AFT Fathom 8, as well as a considerable breadth of new and improved technical features. One such feature is our newly enhanced Relief Valve Junction. A relief valve can still be modeled as Internal, Exit, or Inline Exit, but we now offer four unique opening/closing profiles as well. With these new profiles, you can now directly model many specialty valves which were previously difficult to model accurately! Another very useful enhancement...
