Training Activities Around the World
It's been a busy time for training with several onsite classes in addition to our regularly scheduled pipe flow seminars here in Colorado.
Starting things off was a four day class covering AFT Fathom, AFT Arrow, the Fathom and Arrow Add-on Modules and AFT Impulse for engineers in Iberinco's Bilbao, Spain office. Iberinco is the engineering branch of Iberdrola and is one of Spain's leading power generation engineering firms for nuclear, fossil, hydro, wind and solar power. The flow modeling needs of Iberinco's broad engineering activities is met by the wide capability range offered by AFT's suite of flow modeling software.
After a brief rest we'll be on the road again with onsite training classes to be held over the next few weeks for both ASRC Aerospace and NASA at Kennedy Space Center, Shaw Stone & Webster in Denver, CO and Duke Energy at the McGuire Nuclear Station near Charlotte, NC.
What People Are Saying
We always appreciate receiving feedback and it's especially nice to receive when it's complimentary or provides insite into the benefits AFT software provides our customers. Following are two recently received by email.
Lionel Parton is the Vice President of Engineered Services for Gulf Strategic Partners. As part of GSP's steam systems commissioning services Lionel needs to analyze high velocity gas and vapor flow. Having recently adopted AFT Arrow for his compressible flow modeling activities, Lionel stated; "The first model I built in Arrow on this project I decided to try and build in DFS4 also and compare. DFS4 would not run it. As is so typical of that software, it hit a sonic exit, could not decide what to do next with the 3 other outlets, and crashed. Again thanks, Arrow has really made this project a possibility for us here."
Harold Thomas is an R&D Project Engineer at Air Comm, a leader in aviation systems designs. Having availed himself of AFT's technical support, Harold commented; "Thank You very much for your help. Applied Flow technology is an American Company with good product and good people. It is encouraging every time I deal with folks like you."
Tip of the Month - Adjusting Ambient Pressure
We're not talking about literally adjusting atmospheric pressure here, rather, the ambient reference pressure used in AFT software.
The default value is 1 standard atmosphere, but can be changed as desired. Open System Properties either from the Analysis menu or by double clicking the System Properties check box in the status bar, and select the System Data tab. Enter the desired value in the 'Atmospheric Pressure' field and select the appropriate pressure unit in the adjacent unit drop down box. Gauge pressures, NPSHA and cavitation calculations will reflect this specified atmospheric pressure.
Note that this does not change the value of the "atm" unit which is always a standard atmosphere, 14.69598 psia or 0.10133 MPa.
