would like to model the vaporization/concentration of a liquid spilled in a hallway

StevenD · November 13, 2015, 08:07

I have no idea where to start and wondering if some kind soul could point me in some sort of direction.
I would like to model the vaporization/concentration of a liquid spilled in a hallway that has a known air exchange rate. (Example: spill 8 ounces of alcohol in a 10x10x100 foot hallway with a ventilation system recirculating air at 1200CFM).
I would like know the different vapor concentrations while modifying the volumes and air exchange rates.

I have looked into using OpenFOAM, but the software seems daunting (at this time I have not even figured which solver would be best). I am looking into tutorials that would help, but have not found one that remotely describes my situation.

Questions:
Is OpenFOAM overkill for this type of simulation?
Is there something simpler/better for my application?
What solver would be best?

I don't mind doing the work, I just can't find a starting point. Thanks for any help.

Hi Steven,

I would take a look at sprayFoam. Your case sounds like it would fit in there. Notice OpenFOAM needs metric units!

Thank you! I am looking into using simFlow which supports the sprayFOAM solver. Do you recommend any Linux GUI in particular?

Unfortunately, I have not had any success running simulations (tutorials) with simFlow and openFOAM2.4. The simFlow website states openFOAM up to 2.3.1 and I will need to see if there are issues with 2.4.

Hey,

I am not a professional with OpenFoam and I have no idea how to use OpenFoam from Windows - I gave up after 5 minutes of using google once.
If you decide to use Linux and OpenFoam I recommend Ubuntu 14.04 (LTS - Long term support). If you have no experience take a look at some tutorials of Ubuntu. You can install Ubuntu and Windows along side as well.

Best
