Top 3 Features Engineers Love in AFT Arrow

COLORADO SPRINGS, Colo., USA, July 25, 2018 -  It’s pretty hard to not love everything about AFT Arrow, Applied Flow Technology’s software that models, simulates, and analyzes any kind of gas that can be pumped through a piping system. The software can do anything from measure pressures to thermal analysis. We have been told it “saves a significant amount of man hours” on projects, and time and time again AFT Arrow continues to prove it’s worth around the world by matching data to help facilities expand and increase production.

Don’t take our word for it, you can check it out for yourself with a free demo (or even a full evaluation).


But in the meantime, here are the Top 3 features AFT Arrow users love about the software:

 #1 Don’t Choke - Identify Sonic Choking

High velocity gas systems can be very complex. The effects of compressibility must be accounted for when balancing mass, momentum, and energy. Additionally, there is another limit gas flow can run into – the speed of sound. The behavior of gas flow changes dramatically when Mach 1 is exceeded – pipe friction causes subsonic flow to speed up, but supersonic flow to slow down. This effect prevents subsonic flow from exceeding Mach 1 in a piping system, known as sonic choking.

Sonic choking is a very important effect to consider, as it effectively prevents an increase in flow for a certain upstream pressure. If more flow is required, this poses a problem in many systems. In some systems, sonic choking is used by design as a control feature. AFT Arrow includes the ability to detect and account for sonic choking with minimal user input – even at multiple consecutive locations.

This powerful ability allows an engineering to quickly identify potential issues in a system that may not be immediately obvious with more traditional methods.

#2 The sky’s the limit – Model Complex Networks with Dozens (or hundreds) of Pipes

It’s often difficult to analyze a system involving compressible flow and things become dramatically more complicated when there is branching and recombining flow. Mass, momentum, and energy must balance at every flow split – the effects of which impact the solution in the rest of the system. Every additional branch increases the complexity of a system … and how difficult it is to analyze.

Fortunately, AFT Arrow is available to help tackle this challenge! AFT Arrow allows the definition of an unlimited number of branching flow points and solves the entire system with fundamental compressible flow equations – not with estimations. An accurate solution is critical for complex systems. Rather than simplifying the system so it is easy to solve, use AFT Arrow to account for all the complexities!


# 3 Account for Real Gas Behavior

All mathematical models have certain limitations and simplifications. These are especially prevalent in the analysis of gas behavior. Perhaps the most well-known gas relationship is the Ideal Gas law. 

PV = nRT

This relationship greatly simplifies compressible analysis and works well in many applications. However, real gas behavior does vary from this model. The differences become more evident in more extreme cases with, for example, high temperatures, compressibility, or velocities. In these cases, it’s wise to use a more advanced Equation of State, such as Redlich-Kwong. However, while it’s one of the best methods to use, it’s clearly much more complex and difficult to apply.

But good news! AFT Arrow makes this application easy. The Redlich-Kwong method is the default in AFT Arrow, with the user also able to choose a constant compressibility, three-parameter, or ideal gas method as well. More accurate results are available with AFT Arrow more quickly than using a simplified model by hand.

AFT Announces the Release of AFT Fathom 10

COLORADO SPRINGS, COLORADO, USA – May 2018 – Behind each AFT Fathom model is a real person, a real company and a real problem that at one point needed solving. And that's exactly what customers have done with the help of AFT Fathom for almost 25 years - they solve fluid flow problems. 

With international recognition as the leading software to design, analyze, and solve piping system problems, Applied Flow Technology (AFT) has announced the release of a significant upgrade to AFT Fathom with version 10.

Trey Walters, P.E., President of Applied Flow Technology says, “AFT’s reputation for technical depth is now accompanied by our ability to integrate more than ever with Excel, GIS Shapefiles, CAESAR II, EPANet, ROHR2, AutoCAD Plant 3D, SmartPlant, PDS and CADWorx as well as utilize 2D or isometric pipe model viewing. These factors add a level of ability to not only efficiently model and analyze a system, but to present it to others in a cohesive fashion.”

New features include:

  • Import piping layouts from CAESAR II® Neutral files
  • Import Piping Component Files(*.pcf). from SmartPlant®CADWorx® and AutoCAD Plant 3D, and others.

Liquids And Gases And Slurries, Oh My!

COLORADO SPRINGS, Colo., USA,  May 8, 2018 --  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 liquids, gases, or slurries in your piping systems, AFT can handle it!  The interface and overall functionality for each product is the same.  Therefore, there is no need to worry about having to deal with a separate learning curve for each product. 


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 Arrowand about 80% of how to use AFT Impulse


Also, each product has a few add-on modules.  When you learn the powerful time-saving capability of the AFT Fathom Goal Seek & Control (GSC) module, this knowledge translates directly to using the AFT Arrow Goal Seek & Control (GSC) module.  Dealing with slurries using the AFT Impulse Settling Slurry (SSL) module is no different than working with the AFT Fathom SSL module.

The other significant advantage is that any AFT model file can be imported or exported between any AFT product.  This is incredibly useful because if you need to do a steady-state analysis with AFT Fathom, then find out later that you’re tasked with a waterhammer (surge) analysis project, you can easily open your AFT Fathom model directly within AFT Impulse. 

No need to re-build the model from scratch!  All you would need to do is:

  • Define your transients
  • Section the pipes
  • Specify the simulation duration
  • Then evaluate the results.

 Overall, with the ease of usage, identical interface and functionality of each product, and the ability to transfer models between each AFT product, AFT is your one-stop shop for any liquid, gas, or slurry need you have.
