Vacuum breaker and air valves are useful tools in the industry for protecting pipelines against vacuum or near vacuum conditions. High points in the pipe can be susceptible to these low-pressure conditions during surge events, as pressure waves moving through the system cause a sudden pressure upsurge or downsurge. AFT Impulse can help engineers to...
AFT Impulse 7 has several different tools to analyze waterhammer, including several new features such as Visual Report Animation. This tool offers a new method to understand how different sections in a network interact with each other allowing users to quickly locate points of interest for further analysis, and visually demonstrate the system ...
When completing the analysis on a model, there is nothing more frustrating than having to do the same thing over and over again. Thankfully, using AFT's Piping Layout Wizard you will no longer need to rebuild your CAD, CAESAR II, and EPANET files to analyze the hydraulics using AFT Fathom, AFT Arrow, and AFT Impulse. In addition to GIS sh...
Seeing as this month is water month, we thought this would be a perfect time to highlight some of the great ways that AFT Fathom 10 can help with hydraulic analysis for water distribution, wastewater, and fire water systems. From building the model to exporting and presenting results, we offer several helpful features. We have heard our users...
It is true. New Jersey is a barrier in Spain. I saw it with my own eyes. Bear with me and I will explain.
When I travel internationally I find the people, cultural and language differences fascinating. Last month I was fascinated once again. My blog last month was written while on an airplane as I travelled to Europe (see my July blog When Pipe Stress Analysis Meets Waterhammer Hydraulics: New Waterhammer Guidelines for Engineers). Before going to the ASME PVP conference in Prague (check out this video one of our staff made) I stopped in Spain for 4 days. While there I was fortunate to visit the location of an AFT Impulse project by one of our customers that was a Platinum Pipe Award Winner this year. This case study was published in April. See AFT Impulse™ Matches Data For Pumping Station Check Valve Closure. That pump station photo in the case study is where I visited. Below is a photo of me and the PPA winner David Lozano Solé of AQUATEC – SUEZ Group. For those interested, this project is being presented as a technical paper by David at the 2018 Pressure Surges Conference in Bordeax, France in November. I will be there to help and also present two other papers of my own. So where does New Jersey come into this?
I am sitting on an airplane at this moment somewhere over the Atlantic Ocean and I am excited. Something that has been in the works for 22 years will happen next Monday, July 16 in Prague, Czech Republic. That is where the ASME PVP 2018 Conference will happen and I get to make a presentation.
Last year I helped AECOM, an AFT customer and AFT Impulse user, develop a set of pragmatic internal design documents for their project on handling radioactive fluid transport. Two of these documents provided their engineers guidance on interpreting and applying transient cavitation predictions.We proposed these two documents to the ASME PVP Division and they liked them enough to allow us to publish two new papers at their conference. I will be presenting these papers on behalf of AECOM and AFT.
Here at AFT we are always looking for more ways to bring more convenience and accuracy to our model files. One of the ways we are doing this is with NIST REFPROP, the new fluids database that we have incorporated into AFT Fathom 10 and is coming soon in AFT Arrow 7 and AFT Impulse 7. Unlike Chempak, REFPROP is included at no additional cost to users. In this blog I will highlight a few reasons why you may want to take advantage of this database.
