Humid Air Modelisation with OpenFOAM
 

Hi everybody,

I would like to calculate humid air as a perfect mixture of two miscibles components ( air and water vapor) with OpenFOAM and I would like to calculate the relative humidity of this air and the water vapor pressure. I have already use a equivalent fluid from which I have calculated volume-weighted properties. But this time, I would like to have two different parts.I would like to know the way to do with multiphase flow model (reactingParcelFIlmFoam, interPhaseChangeFoam). Does anybody know how to do it?

Thank you very much,

Best regards,

Miki

Hello everybody,

Nobody knows how to do? Any insight will be very helpful!

Thank you so much,
Best regards,

Miki

I have a similar problem, does anybody knows how to solve?
Thanks in advance!

A reference paper hint
 

Dear all,
we developed a specific solver for this problem :), including evaporation and condensation effect, with conjugate heat transfer.
You can find the model explained in "P. Sosnowski, A. Petronio, V. Armenio, Numerical model for thin liquid film with evaporation and condensation on solid surfaces in systems with conjugated heat transfer, International Journal of Heat and Mass Transfer 66 (2013) 382–395".

Hope it helps

Hi Andrea,
I am trying to implement the above suggested paper model in OpenFOAM. It will be really helpful if you can let me know about its validation performance. I understand that you might have done more validation of the model mentioned in paper. Please let me how did this model performed w.r.t to your test case.

The paper only deals with a laminar flow int the pipe where it is comparing its result with experimental finding. Please let us know if you have more comparison.

Thank you

more works done with the model
 

Hi,
yes we worked a lot on this model. If your're interested in a turbulent flow have a look to:
Cintolesi, Petronio, Armenio, "Large eddy simulation of turbulent buoyant flow in a confined cavity with conjugate heat transfer"Physics of Fluids 27(9): September 2015 DOI: 10.1063/1.4930815
and
Cintolesi, Petronio, Armenio,"Large-eddy simulation of thin film evaporation and condensation from a hot plate in enclosure: First order statistics", International Journal of Heat and Mass Transfer 101:1123-1137 · October 2016 DOI: 10.1016/j.ijheatmasstransfer.2016.06.006.
The paper with second order statistics analysis is under review.
Moreover we introduced the radiation modeling in the CHT model as you can check in
Cintolesi, Nilsson, Petronio, Armenio,
"Numerical simulation of conjugate heat transfer and surface radiative heat transfer using the P1 thermal radiation model: Parametric study in benchmark cases",International Journal of Heat and Mass Transfer 107(April 2017):956–971 April 2017 DOI: 10.1016/j.ijheatmasstransfer.2016.11.006.
Hope it helps!

Thank you so much Andrea for your reply. let me go through the papers mentioned by you.
Allow me to ask for on one more help if it is possible for you. If there are no copyright issue, will you be able to share the code that you have implemented in OpenFOAM. it will be a great help to take the study further.

Please let me know your thought.

Thanks and Regards
