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 8 turned...

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. The...

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.

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 parameters in your model, re-run the...

How AFT Impulse Can Help Engineers Comply With ASME Codes

Summary Engineers are often responsible to design systems to comply with codes and standards. In recent years codes that apply to waterhammer and surge pressures have become more prominent. Increasingly AFT Impulse is being used to help engineers comply with such codes. Once AFT Impulse has calculated the maximum pressure due to a transient event, what shall the designer do with this value? The answer to this question depends on the code that is being used as the piping design basis. In this article, we’ll be discussing how two important piping design codes - B31.4 and B31.3 - deal with surge...
