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...
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...
Many of you are aware that AFT released the ANS module for AFT Fathom and AFT Arrow last year to help engineers minimize the cost of their system and maximize reliability. You can check out this blog I wrote last year for a quick recap on the capabilities of ANS. Let's talk a bit more about what information you need to use the ANS module by introdu...
Recently AFT announced our new release of Fathom 11. With our new release we have been working hard to create a more robust and faster version of Fathom. Along with improved performance we have added several new tools that have been requested by customers. Here is a quick summary of the top 5 new features that you can look forward to in Fath...
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...
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...
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...
