The Drones Are Coming! The Drones Are Coming!

News on the development of drones (also known as Unmanned Aerial Vehicles or UAVs - or UUVs if underwater) is on the rise. The applications for UAV technology to support engineering activity seem endless. However, as with all new technologies, UAVs can potentially negatively interfere with pre-existing operations, laws and regulations, general accepted practice, as well as common decency. Pipelines - drones are being considered as a replacement for helicopters and other manned aerial vehicles in monitoring pipeline safety and leak detection. See  Drones could be used on North Dakota oil fields . Power and Mining - drones are being considered...

When Pipe Flow Modeling Is Not Enough

Within the world of pumping system specialists there is a wide range of areas of domain expertise. I was reminded of this earlier this month while attending the AFT Calgary User Group meeting sponsored by AFT's Canadian channel partner CodeCAD. One of the invited speakers, Jordan Grose of Beta Machinery, used several areas of domain expertise to solve a waterhammer problem in the field. I will discuss more about Mr. Grose's presentation later in this article.

Why Gases Are More Complicated Than Liquids: And How the New AFT Arrow 5 Can Help

Several generations of engineers ago engineers realized that performing calculations on gas flow is a lot more difficult than for liquids. As a result, the bulk of what is gas flow engineering history has revolved around how to treat gases as liquids. Another large portion of history is how to simplify gas flow equations down to simple isothermal relationships. In other words, the majority of gas flow engineering historically is about how to take short cuts with gas flow calculations. Today it is no longer necessary to take short cuts. But all too often we see engineers doing just that. AFT...

Burst Pipe at World Cup Stadium Showers Media With Pervasiveness of Fluid Systems

During the 2010 World Cup I happened to be touring Spain and Italy with my family. I was in Spain for a week during the early rounds before anyone had any idea that Spain would emerge as the eventual winner. I watched one of the games at a Spanish family's house (who were personal friends in Barcelona) while we were visiting for dinner. By the time I got to Italy the Italian team was on the verge of elimination and the locals I talked to were quite deflated about that development.  Those of you who are from such nations understand the...

The First Visual Software for Windows Released 20 Years Ago This Month

Applied Flow Technology has been an innovator and industry leader since its founding in 1994. AFT Fathom ™ was the first of its kind – a graphical, drag-and-drop platform for modeling pipe system hydraulics. AFT Fathom was released commercially twenty years ago this month on April 12, 1994. The history of how AFT Fathom was named is interesting in its own right and was discussed here - Where Did the Name "Fathom" Come From ? The list of commercial software “firsts” for AFT Fathom is long and impressive. Here is a summary of some of the more important ones: Visual, drag-and-drop...
