What Is Transient Analysis?

 pressure at Valve Inlets Figure 14 - Transient pressure at Valve Inlets for Scenario 2 of the AFT Impulse transient simulation where Valve C closes linearly in five seconds. Note the initial pressure is about 200 psia, about 10 psi higher than Scenario 1.

You're tasked to perform a transient analysis of a piping system and it would be really helpful if there was a good software tool out there to help you.  Well, you've come to the right place because AFT has great solutions!  But our first question is, "What kind of transient analysis are you trying to do?"  You might s...

Know Your Pump & System Curves - Part 3

SystemImages

In the final "Know Your Pump & System Curves" blog series, I am going to discuss the complexities behind pump vs. system curves for systems with pumps in series and parallel configurations. Multiple pumps in series configurations are relatively straight-forward and will be discussed briefly. Operating pumps in parallel configuration involve a f...

Know Your Pump & System Curves – Part 2B

In this blog, we dive further into pump and system curves for complex systems.  The examples include demonstrating system curves changing over time and when multiple system curves exist for a single system with multiple pumps in different locations of the system.  Let us re-visit the multi-branched system example from the previo...

Know Your Pump & System Curves – Part 2A

Many users enjoyed my previous blog, "Know Your Pump & System Curves – Part 1" and greatly anticipated the release of Part 2. I'm going to split Part 2 into two separate blogs: Part 2A Brief discussion on why system curves matterPump & System Curves for multi-branched piping systems§How you can have different system curves for the...

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 trans...

6 Reasons Why You Need Flow Analysis

1. Guarantee the system will work according to design2. Understand complex system interactions3. Ensure design requirements are still met in different operating cases4. Evaluate system dynamics of surge and non-surge related transient operation5. Easily plan for future expansions and system modifications6. Empower clients to better understand their...

6 Reasons Why Flow Analysis is Necessary

To all of the engineers reading this article, we made it! Whew! Reading a three-part series is like running a marathon. Way to go! If you are new to this series, we encourage you to read this article as well as the previous two: Part 1: Six Reasons to Use a Flow Analysis and Part 2: Flow Analysis Is Neglected. In this article are six reasons e...
