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...

The Quest For Controlling Energy Costs

One of my favorite lines from the movie Apollo 13 was when an engineer exclaimed, “Power is everything!”. Nothing happens without power. Power, the rate at which energy is used, underlies everything in modern society. Trends in energy economics are impacting industries and entire nations. Some recent articles about European chemical production and refining illustrate this.   EU chemical industry on the verge of collapse   from Processing Magazine 2013 "The European chemical industry is in grave danger and a large part of it might close down within the next 10 years… The biggest problem is that chemical manufacturing is heavily...

Recent Nuclear Fusion Breakthrough Supported by AFT Arrow

It is always interesting to see items in the news where our software has played a role. Last week a breakthrough in nuclear research was achieved at Lawrence Livermore National Laboratory 's (LLNL)  National Ignition Facility (NIF). According to science journal Nature, "Using the world's most powerful assembly of lasers, a team of researchers say they have, for the first time, extracted more energy from controlled nuclear fusion than was absorbed by the fuel to trigger it — crossing an important symbolic threshold on the long path toward exploiting this virtually boundless source of energy." The full news article from Nature can be found...
