What do NASA, DuPont, GDF Suez and the University of Arkansas know about AFT software that you may not? Watch it here!

  Introducing Applied Flow Technology Fluid transportation is an integral part of today's society. AFT software products have emerged as world leaders in helping engineers move fluids more safely and efficiently. There are countless examples of this. We have chosen four such stories to help engineers understand how our products can help them solve problems and improve their engineering designs and operations. We developed a video to tell this story. Watch it here! DuPont The first story talks about how AFT Fathom  helped DuPont solve a serious operational problem in three newly designed slurry systems. I co-authored a technical paper along...

Using Three Way Valves in AFT Fathom

AFT Fathom provides a Three Way Valve which increases the Engineer’s capability to model system control. The Three Way Valve Properties Window shows the three connecting pipes in drop-down lists, which allows users to specify which pipe is the combined flow pipe, and which two are the split flow pipes. By entering the loss profile through each flow path, and then by selecting the actual percent open, Fathom will calculate the actual loss values for each flow path. Using the Three Way Valve in conjunction with the Goal Seek & Control module (GSC) increases the Engineer’s capability to model I&C logic...

World Languages and Waterhammer

The demand for our AFT Impulse waterhammer modeling software and associated training seminars has been growing steeply in recent years. I frequently travel internationally to teach  seminars on waterhammer. When I do I make it a point to find out what the engineer's local language calls waterhammer. For those who are not familiar with waterhammer, it is a transient phenomenon that occurs in liquid pipe systems when some event causes a departure from steady-state flow. The English language term waterhammer is a bit confusing. As it has the word "water" in it, it implies a process involving water. But the English term...

Curious About Modeling Relief Valves?

Relief valves can be modeled in four different configurations with AFT products and they are shown in the figure below.  The required inputs for modeling a relief valve are the valve type, cracking pressure, valve loss model, and the exit pressure in the case of relieving to the atmosphere.     There are three types of relief models available:  Internal (Cases 1 & 1a), Relief Valve at Exit (Case 2), and Inline Exit (Case 3).  In cases 1 and 1a, the relief valve is relieving into vent piping downstream of the valve.  Note that there is initially no flow in the pipe...

Who said pipe flow can’t be fun? Disney’s World of Color water spectacular

In 2010 the Walt Disney Company created a mind-boggling new night time show called World of Color at the Disney California Adventure theme park which is part of Disneyland Resort in Anaheim, California. For anyone who ever doubted that flow can be fun, you need to see this show! A few weeks ago I saw World of Color while in California with one of my kids. While it was not the first time I have seen the show (OK, I think it was the eighth time), my son and I were reminded of how excellent this show is. There is nothing else...

Annotation Images

One of the many new features in Fathom 8 is the ability to show images in the annotation box. This simple feature will allow the engineer to easily and clearly communicate a vast array of information through the Workspace and Visual Report.   To add an image to the Workspace or Visual Report, as seen above, select the Annotation tool from the toolbox. Then select the “Line/Arrow/Image” tab and specify the file path to your image. Once the image is selected, click OK. The image box shown on the workspace can be easily moved and resized.

AFT Fathom 8 and the Future of AFT

AFT Fathom 8 began shipping last week. And we are excited. The release of AFT Fathom 8 coincided with the unveiling of our new logo, new website and newly branded material. It is not an understatement to say this represents a new era for AFT. What does all of this mean for the future? The new, more modern look and feel of AFT Fathom 8 is based on a new underlying architecture. We will be working hard to move all of our other products to this architecture as quickly as possible. Our best guess is that AFT Impulse 5 will be available...
