Case Study: DuPont Saves Millions of Dollars With AFT Fathom on Slurry System Operational Problem

DuPont experienced severe operational problems on a new product line that put at risk a multimillion dollar investment. The system involved pumping of a non-Newtonian fluid which behaved as a Power Law fluid. AFT Fathom ’s unique capability to model valves and fittings was critical to identifying the cause of the problem and guiding the solution. DuPont engineer Dan Wood teamed with AFT President Trey Walters to present a technical paper this week at the 28 th International Pump User Symposium in Houston, Texas. There they presented the problem and resolution which involved a new valve and fitting calculation method developed...

AFT Fathom 8...Worth the Wait

We at Applied Flow Technology are really excited about the new version of AFT Fathom 8 coming in September. Once our customers get their hands on it we are confident they will be equally excited. This version represents the most significant upgrade since AFT Fathom 4 was released in year 2000. It will further establish AFT Fathom as the world's leading pipe flow modeling tool. The prices are increasing soon so if you are planning to order new AFT Fathom licenses or SUM annual support do not delay. Read further for more details. The effort to move AFT Fathom from version 7 to...

Increasing Heat Exchanger Accuracy for Large Temperature Differences and Non-Linear Heat Capacity

Many times when modeling heat transfer using heat exchangers in AFT Fathom , significant temperature differences across the heat exchanger can have a major impact on the accuracy of the heat transfer results.  This can especially become a problem with non-linear heat capacity relationships.  The heat transfer across the heat exchanger in the model below is calculated from the temperature difference across the heat exchanger and the arithmetic average heat capacity. One way to enhance the accuracy of the heat transfer results is to model the single heat exchanger junction, J2, as multiple heat exchangers as shown in the below model....

AFT Software Pricing Will Change in September with the Release of Fathom 8.

The next generation of AFT Fathom will be released in September 2012, offering engineers unprecedented modeling and user interface capabilities. Pricing Highlights: Second and additional seats, on the same purchase, of a network license will receive a 10% discount. Customers who maintain a current Support, Upgrade & Maintenance (SUM) subscription on their network licenses will receive a 10% discount on future purchases of that product.  The AFT Fathom Cost Estimation (CST) and Non-Settling Slurry (NSL) modules will no longer be offered as separate items but will be included as part of the core AFT Fathom 8 product. Package discounts for buying...

Jumping Specification Windows

In the process of making specification changes to a sequence of pipes or junctions, one may find it easier to jump from one pipe (or junction) to the next without closing the current specifications window. This can be accomplished by clicking the “Jump” button in the specifications window. Clicking the Jump button will open a dialog where the next pipe or junction number can be selected. Once the selection is made, clicking on the jump button will advance the existing specifications window to the selected pipe or junction number. To make things even faster, pressing F5 within an active specifications window...

The Future of Engineering - Part 2

This article is the second in a two-part series on the future of engineering. Part 1 was discussed last month in The Future of Engineering - Part 1 . I was teaching a training class a few months ago at Kennedy Space Center in Florida and had the good fortune to get a guided tour of the space center by "Rob," one of the attendees in my class. I wrote about this tour in  My 50th Anniversary Visit to the Site of John Glenn’s First American Flight Into Space . Rob is an engineer's engineer who tinkers in his garage on weekends. Rob...

Graph Sets

In all of our core products ( Fathom , Arrow , Impulse , Mercury , Titan ), we offer the ability to save graph sets. This has the potential to save a lot of time when reviewing multiple graphs of different parameters. In order to define a graph set, first construct and customize the graph you would like to review. Then open the “Select Graph Data” window from the View menu and click the button “Save Set As…”. After entering a graph set name, click ok, and you have just created a graph set! At this point you can modify any...
