Pulsation Frequency Analysis Takes a New Turn

In recent years, engineering efforts have been increasingly focused on analyzing and preventing detrimental pulsations in pipelines. One major source of these pulsations is caused by acoustical resonance. Undesirable acoustical resonance happens when pressure pulses (the source of which is often a positive displacement pump) excite the system's nat...

Iso love the new Pipe Drawing Mode!

Have you ever wanted to show the three-dimensional nature of your piping system in AFT applications? Maybe you are building a model from an isometric reference drawing. Or maybe you are incorporating your model into a report and want to represent the x, y, AND z axes.

Whatever the reason may be, the great news is that AFT Fathom 10 includes a new Isometric Pipe Drawing Mode!

Paint a Clear Picture Faster Than Ever with AFT's New Excel Export Manager

​AFT Applications have the potential to generate overwhelming amounts of output information. The extensive output customization and graphing capabilities within our products are excellent when building a model and quickly reviewing its behavior. However, it can be difficult to get exactly the data you want in an easy to manipulate form for additional calculations or polished client reports.

To help address this, AFT Fathom 10 is introducing the powerful new ability to export user-selected data directly to Microsoft Excel. Get only the data you need, exactly where it is needed.

Learn About the Acceleration Head and How To Model It

The pistons, or diaphragm of a reciprocating (positive displacement) pump causes a cyclical variation, typically in some sinusoidal form, of both flow in pressure in a piping system. The magnitude varies, depending on the type and design of the pump. What is acceleration head? Acceleration head is the energy required to change the velocity of the liquid in the system from an at rest, or zero condition, to some non-zero value. To help us understand acceleration head a little more clearly, you could compare it to a race car. In a drag race, the race car will accelerate to some maximum velocity,...

Determine Your Pumps BEP and Know API-610's Recommendations

What is BEP & why is it important? Every pump has an ideal range of operation where the pump is most efficient. The peak of the efficiency curve is known as the best efficiency point (BEP). Determining how far your pump is operating from its BEP is critical to increasing pump reliability and efficiency as well as meeting API 610 recommendations. AFT Fathom models pump curves with efficiency data and will determine the margin between the simulated operation of the pump and the actual best efficiency point. Our friends at Empowering Pumps shared an article titled, "Some Effects of Operating Pumps Away from Best Efficiency Point" which...

Planning for Success by Predicting Failure – Maximizing Reliability During Pump Selection

What comes to mind when you hear the expression “planning for failure”? For some, it carries the negative connotation that failure is the direct result of a design – intentionally or otherwise. Benjamin Franklin said; “If you fail to plan, you are planning to fail!” and I believe he would agree that any good plan addresses potential failures. In fact, not "planning for failure" as an element of a system is essentially failing to plan and therefore inviting unexpected and unmitigated failures. Life Cycle Cost One of the many reasons to avoid failure when possible is to reduce cost. When a...

Reaching Equilibrium: System Energy Balance in AFT Fathom and AFT Arrow

AFT Fathom and AFT Arrow both have the powerful ability to model heat transfer in pipes and heat exchangers, allowing you to represent these critical features of temperature-sensitive systems in your hydraulic model. However, without being able to see the affect heat transfer has on an entire system these features would be of limited usefulness. One of the most powerful aspects of AFT’s implementation of heat transfer is that energy is balanced across the entire system. For example, you can observe changes in pump or control valve operation when adding heat transfer to a remote part of a system. Looking at...
