Size Up Your Options Using the ANS module

When working on a new piping system, there are many factors that must be taken into account: meeting customer demands, following industry standards, and maintaining effective system operation to name just a few. As a busy engineer, it is important to address all of these concerns in the short time frame available to you. AFT's new Automated Network...

Fluid Mechanics 101 – The Class That Changed My Life

I was 20 years old and 18 months away from finishing my formal education. Forever. I was well on my way to being a…structural engineer. Wait, that must be a typo. Structural? Really? Where did the fluids come in? I really liked structural mechanics and that was where I was focused for the first 2.5 years of my mechanical engineering studies. My cla...

Looking to relieve pressure? Let's talk about Relief Valves in AFT Impulse.

In any complex piping system, one of the most serious scenarios considered during a safety or HAZOP study is over-pressurization. If the pressure in the system reaches a high enough pressure, rupture can occur, leading to expensive repairs, significant system downtime, and even loss of life. In most cases, proper use of relief valves can mitigate o...

Applying Communication Time: Let’s Talk About Your Impulse Result/Event Relationships

 I have received questions from clients using AFT Impulse where they ask something like "I closed this valve. Why is the maximum pressure spike way over there and not at the valve?" This comes from years of developing a "common sense" adapted to steady-state flow. With steady flow, a change between states of equilibrium has a local effect that...

My (Not So Secret) Disney Obsession

My name is Trey and I am a Disney geek. A real, true Disney geek. What does that have to do with Applied Flow Technology and pipe flow simulation? Well, a lot actually. Read on if you want to know more… This year is AFT's 25th anniversary and I have been doing a lot of reminiscing. About many things. I have been a Disney geek since I rode Dumbo at ...

Two for One: How Dependent Design Cases Help Automatically Size Networks to Satisfy Multiple Operating Scenarios

With the release of the Automated Network Sizing (ANS) module for AFT Fathom and  AFT Arrow, network sizing has never been easier. The ANS module utilizes Intelliflow, a technology previously featured in AFT Mercury and Titan, to evaluate slight design deviations to automatically size pipes, valves, and pumps for a system as a whole.  In ...
