pros&cons about "software flow of fluids"

pros&cons about "software flow of fluids"

(OP)
Dear Forum Members,

Does anyone has any experience with "flow of fluids (FofF)software"?
http://www.flowoffluids.com/software.htm

Any other suggestions about programs like FofF for analyzing thermal-hydraulic systems would be appreciated...

Best Regards,

No, but it looks promising.  I might try the demo, if I get some time.

RE: pros&cons about "software flow of fluids"

There are hundreds of these sorts of programs.  All of them have strengths (i.e., areas where they put particular focus) and all of them have weaknesses (i.e., bugs or types of problems that they don't handle as rigorously as they should).  

When I get a new one for evaluation I see if it can handle a system that I used to operate.  I put in all the sources of gas, all the deliveries of gas, all the piping.  Then I put in flow rates and off-system delivery pressures for a case that I measured in the field.  At that point I look for levers to tweak to try to match measured pressures with model output.  If I can match all the wells within 5 psia then the model has addressed the issues that I most often have and I use or recommend it.

Not verifying that the model can solve the kind of problems you face is a very bad idea.  The best example I have is a very well known program that has a bug that creates a strong preference to flow gas from small numbered nodes to large numbered nodes.  This preference is so strong that system modifications that reverse flow in a segment will show no-flow in the new pipe.  The bug is still in the latest release and the company was notified of it by at least 6 engineers as far back as 1996.  The only way to find this sort of bug is to build a model to see for yourself.

I recently sent my calibration model to a vendor and he was able to match the flow for two different sets of conditions (no WYSIWYG model has ever been able to do that before).  I bought the software (not cheep, but they set up a payment plan for me).  When I had a real project I tried to use the new software and found that they don't allow inputting suction pressure for a compressor (only discharge pressure and hp).  The main things I was trying to solve for was hp requirement and discharge pipe size (i.e. discharge pressure).  The vendor had gotten around this limitation by using my solved model to get hp and discharge pressure on the calibration case.  It was worthless for the problems I typically work on.

In short, it may be a great program, but you need to verify that for y0urself.

Isn't this Crane's software based on their book?

Yes! it is based on Crane's software...
