Campus Steam System Redesign Moves Forward After Data Matches AFT Arrow Model

2013 Platinum Pipe Award Winner - Correlation to test/field data   Schuyler Engineering was asked to confirm a 2010 study that recommended that Rockland Psychiatric Center convert to using low pressure steam. Modifications would cost over one million dollars, so constructing a model would give further confidence to the previous study and determine if the conversion to low pressure steam should proceed.     Click here to read the case study and learn how AFT Arrow test results validated previous study results.   Schuyler Engineering is a professional consulting firm specializing in the evaluation, engineering, design, permitting and construction supervision of heating...

Announcing the Winners of the 2013 Platinum Pipe Award!

Now in its 9th year, the AFT Platinum Pipe Award recognizes excellence in piping and ducting system modeling using AFT software. We are pleased to congratulate the winners of the 2013 AFT Platinum Pipe Award! For the first time this year, we have awarded an honorable mention. Use of Software Features and Model Creativity Winner: Jordan Grose, Beta Machinery Analysis, Canada AFT Impulse was used to solve significant waterhammer occurring after pump trip and check valve closure. Assigned flow junctions were manipulated to make the pressures match at the pump discharge check valves, showing a creative use of the software’s features....

Challenges Executing Fluid Flow Projects?

Resource planning for engineering projects can often be a challenge.  Just when you’ve finished finding projects for all of your staff, an unexpected client call occurs which requires immediate additional technical personnel.  Or, your best fluid flow engineer has recently left the company – just in time for you to be awarded a large integrated team engineering project in which they were proposed to play a key role.         Purple Mountain was originally founded to provide consulting support for AFT software products and has since evolved to assist clients with a broad range of fluid flow challenges. If you...

Modeling a submerged pump in AFT Impulse

In AFT Impulse you can directly model a submerged pump. First, you will define your pump data exactly as you would normally, however you will only draw the discharge piping and not a suction piping. After doing this, you will check the box “Submerged Pump” at the bottom of the Pump Specifications Window. You now have an additional required input field. The “Suction Pressure” can be entered as a Head (HGL) or a Pressure. When entered as a Head (HGL) value, this value is the actual liquid elevation in the supply reservoir. When entered as a pressure, this is the actual...

Using Three Way Valves in AFT Fathom

AFT Fathom provides a Three Way Valve which increases the Engineer’s capability to model system control. The Three Way Valve Properties Window shows the three connecting pipes in drop-down lists, which allows users to specify which pipe is the combined flow pipe, and which two are the split flow pipes. By entering the loss profile through each flow path, and then by selecting the actual percent open, Fathom will calculate the actual loss values for each flow path. Using the Three Way Valve in conjunction with the Goal Seek & Control module (GSC) increases the Engineer’s capability to model I&C logic...

Case Study: DuPont Saves Millions of Dollars With AFT Fathom on Slurry System Operational Problem

DuPont experienced severe operational problems on a new product line that put at risk a multimillion dollar investment. The system involved pumping of a non-Newtonian fluid which behaved as a Power Law fluid. AFT Fathom’s unique capability to model valves and fittings was critical to identifying the cause of the problem and guiding the solution. DuPont engineer Dan Wood teamed with AFT President Trey Walters to present a technical paper this week at the 28th International Pump User Symposium in Houston, Texas. There they presented the problem and resolution which involved a new valve and fitting calculation method developed by AFT...

Graph Sets

In all of our core products (AFT Fathom, AFT Arrow, AFT Impulse), we offer the ability to save graph sets. This has the potential to save a lot of time when reviewing multiple graphs of different parameters. In order to define a graph set, first construct and customize the graph you would like to review. Then open the “Select Graph Data” window from the View menu and click the button “Save Set As…”. After entering a graph set name, click ok, and you have just created a graph set! At this point you can modify any parameters in your model, re-run...
