Modeling Fans, Blowers and Compressors - Oh My!

For gas systems flow is driven either by a pressure difference, or by a turbomachine. AFT Arrow allows users to model turbomachines such as fans, blowers and compressors. For this blog we'll talk about what differentiates these three options, and how to model them using AFT Arrow.    Definitions and Types Fans, blowers and compressors all...

Back to the Basics: Calculating and Defining Head

While thinking in terms of pressure is often intuitive for engineers, thinking in terms of head can be more challenging. You may be surprised by the number of cases and questions that come to the support team here at AFT about the basic definition of head, and how it relates to hydraulic modeling. Let's get back to the basics with how head is defin...

Where to Start with Pump Startups

Any time a rapid transient occurs in a piping system, there is a chance for unexpected surge to impact the system. Though system shutdowns account for many surge events, pump startups can cause water hammer as well. For this blog I am going to cover the basics of setting up pump and valve transients for the startup case in AFT Impulse 7, as well as...

Applying the Improved ATKF Method for Laminar and Non-Newtonian Flow

If you have worked with Non-Newtonian fluids or low velocity systems in AFT Fathom or AFT Impulse before, then it is likely that you have worked with the Adjusted Turbulent K Factor (ATKF) method before. The ATKF method can be used to adjust K factor data developed for turbulent flow conditions to better predict loss in the laminar f...
