You Should Combine Your Pipes

  One of the many powerful features in AFT Impulse is the ability to calculate transient forces during a waterhammer/surge event (See " Evaluating Dynamic Loads in Piping Systems Caused by Waterhammer " white paper). The resulting transient forces can be exported into a pipe stress analysis software. Pipe stress analysis care about what the tr...

6 Reasons Why You Need Flow Analysis

1. Guarantee the system will work according to design 2. Understand complex system interactions 3. Ensure design requirements are still met in different operating cases 4. Evaluate system dynamics of surge and non-surge related transient operation 5. Easily plan for future expansions and system modifications 6. Empower clients to better understand ...

Why Flow Analysis Is Neglected

We hope you enjoyed our previous article on the Top 6 Reasons Your Design Should Include Flow Analysis. But now… let's get a bit serious and talk about three main reasons why flow analysis is neglected during the design process. It could be straight neglect, or unconscious neglect. Either  way we will open the conversation and provide some ins...

Intermediate Elevations and Splitting Pipes

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...

Liquids And Gases And Slurries, Oh My!

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...

What Does “Head (HGL)” Mean for Submerged Pumps and Exit Pressures?

In AFT Fathom and AFT Impulse , it is possible to model a submerged pump where a short and possibly frictionless suction pipe for the pump’s inlet does not need to be modeled.  When modeling a submerged pump, there are two options available for specifying the system inlet boundary condition at the pump suction.  As shown in Figure 1 below, the Submerged Pump’s Suction Pressure can either be specified as “Head (HGL)” or “Pressure”.   Modeling a submerged pump is not the only time where the “Head (HGL)” or “Pressure” choices will arise.  If an Exit Valve (i.e., a valve that...
