Several generations of engineers ago engineers realized that performing calculations on gas flow is a lot more difficult than for liquids. As a result, the bulk of what is gas flow engineering history has revolved around how to treat gases as liquids. Another large portion of history is how to simplify gas flow equations down to simple isothermal relationships. In other words, the majority of gas flow engineering historically is about how to take short cuts with gas flow calculations.

With the release of AFT Fathom 8 and AFT Impulse 5, there is an incredibly useful new feature available on the Workspace called the "Quick Access Panel".  This feature allows you to quickly and easily work with several useful features of the software in one area such as the Scenario Manager, Pipe and Junction Inspection, Workspace Overview Map, the Checklist, and ability to activate the add-on modules. Scenario Manager Access to the full Scenario Manager capabilities exists in the Quick Access Panel.  Add new scenarios, clone scenarios, promote scenarios, re-order scenarios, add notes for scenarios, etc. Properties The Properties tab in...

An excellent new feature of AFT Impulse 5 is that it is possible to estimate the pump inertia, specific speed, and four quadrant data sets directly within AFT Impulse 5!  No more need to perform external spreadsheet calculations for these estimates. In addition to that, AFT Impulse 5 can use the entered pump and power/efficiency curve to perform these estimates which makes things much easier and efficient!! First step is to enter pump curve data and generate the curve fits as shown in Figure 1. Figure 1:  Pump Performance Curve from Entered Data   Next, click on the "Transient" tab of...

There are two good reasons you should care that Applied Flow Technology is celebrating it's 20th anniversary this year.

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?

Well, it turns out lots of people. My first experience with "funny fluids" was in graduate school. One of my fluids professors had recently completed his doctoral thesis on funny fluids also known as non-Newtonian fluids. I got to see some of his graduate students do some crazy experiments with polymer additives to otherwise boring Newtonian fluids.

We are excited about all the new features coming in our AFT Impulse 5 waterhammer and surge modeling software. We plan to release this much anticipated new version before the end of the year.
