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...
Hello AFT readers! It has been quite a while since I have written a blog for you all. I had a recent discussion with a user and discovered a couple pain points that may be common. We did not have any blogs on the topics yet and I figured it was time to get back in the game and write another blog for our readers! The pain points were: 1. Modeling sy...
In district heating projects, hot water is the most commonly used heating medium. In order to ensure the user's heat load requirements, it is necessary to analyze and calculate the flow balance of the entire district heating system to ensure that different cases can meet the requirements of end users.
AFT Fathom is practical fluid dynamic simulation software used to calculate pressure drop and flow distribution in liquid piping and ducting systems. I think AFT Fathom is a great choice for district heating projects.The district heating network model of this project is bigger, and it includes the long supply line and return line, several booster pump stations, about 50 end users(exchangers), many control valves. This project has been running for 2 years, but some end user cannot get enough heat, so the owner hope us to get the reason.
I am sitting on an airplane at this moment somewhere over the Atlantic Ocean and I am excited. Something that has been in the works for 22 years will happen next Monday, July 16 in Prague, Czech Republic. That is where the ASME PVP 2018 Conference will happen and I get to make a presentation.
Last year I helped AECOM, an AFT customer and AFT Impulse user, develop a set of pragmatic internal design documents for their project on handling radioactive fluid transport. Two of these documents provided their engineers guidance on interpreting and applying transient cavitation predictions.We proposed these two documents to the ASME PVP Division and they liked them enough to allow us to publish two new papers at their conference. I will be presenting these papers on behalf of AECOM and AFT.
It's time again for that discussion. Which discussion, you ask? I am talking about the discussion regarding the onward march of technology, automation and job creation and destruction. If international observers are mystified by President Trump, know you are in good company because he also mystifies many Americans. But he represents a trend that is not just American as seen by the Brexit vote and similar "national interest first" thinking in other parts of Europe and the world.
A large concern in America is the perceived decline of manufacturing in the USA. An article last month in Mechanical Engineering magazine "The State of American Manufacturing 2018" brings up some complicated issues that got me thinking.
So, let's start at the beginning.
Until a week ago, when I thought of Khalifa Tower, I thought of the Mission Impossible (Ghost Protocol) movie with Tom Cruise' death-defying action scenes hanging off the outside of the building. Now, I think of my visit there a week ago.
At 828 meters (2,717 ft) tall, Burj Khalifa (also known as Khalifa Tower) in Dubai, UAE, is the tallest building in the world – at the moment (more on that later).
As Khalifa Tower reaches to the sky physically, Dubai reaches to the sky metaphorically. I have visited about 30 countries and have never seen anything like it. Twenty years ago, there was mostly sand. And now?
Tip: If you know how to use AFT Fathom, then you are over the learning curve by about 90% when it comes to knowing how to use AFT Arrow, and about 80% of how to use AFT Impulse. One of the best advantages to AFT software tools is they offer a full solution for any single-phase pipe flow analysis calculations. Whether you are dealing with liqui...
AFT Applications have long had several options for the export of output data. Data can be directly copied and pasted into other Window's applications, and entire sections of the output can be exported to preformatted, delimited, or Excel formats. However, these options can be inflexible or require significant overhead. AFT Fathom 10 is introducing ...
