looking for a thin film model
 
Dear All,

I have seen a lot of presentations around internet about thin film modeling in OpenFOAM but I could not find any solver available.

Take a look at some sites:
http://web.student.chalmers.se/group...SlidesOFW5.pdf
http://www.csi.tu-darmstadt.de/media...sak1_intro.pdf
http://www.csi.tu-darmstadt.de/media...ledsystems.pdf

Does somebody know where to find those models?
Or even whether or not they are freely available?

Regards,

Guilherme

A part of this is released, but some work is still ongoing and until it is completed the complete liquid film is still not released. Please drop an E-mail either to Zeljko or myself to discuss the details if you have a concrete collaboration in mind.

Dear Prof. Jasak,

Thank you for your quick and kind reply. Yes I do have an application in mind and a potential development to carry out but it is still in phase of feasibility and fund raising.

Certainly I will send you an email directly when I have more concrete collaboration proposal.

Regards,

Guilherme

Dear Prof. Jasak,

I'am very interested to model a type of condensation using the published thin film model. Is it right that the model also is called finite area model (FAM)? Do you have some more mathematical an numerical information about this model for me. I'am searching for some papers like that from BAI and Gosman ore Stanton. Can you tell me where I can found them.

Hi Stefan,

I believed that finite area method (FAM) is already implemented in OpenFoam 1.6-ext but not released completely as the solvers and tutorials are not available. This is a result of several yerars of research of Profs. Jasak and Zeljko in the area of liquid film movement. See presentations in my first post.

Are those papers cited by Karl Meredith, who works with FM Global and OpenCFD with water film simulations? You will find those papers in SAE library on-line for few bucks. Probably FMGlobal will release something (part of the work) related to water film and sprinklers impingement because they did it for fireFoam when working with OpenCFD. However, there is no indication when they plan to do it.

See the link, it may help you:

I hope it helps.

Prof. Jasak,

Hello again.

Could you tell us what is the main difference between OF1.6-ext and OF2.0 regarding thin film models? Do you have tutorial cases for FAM and thin film classes implemented in OF1.6-ext?

Another thing, I noticed that OF-1.6ext had better convergence than OF1.7.1 in a low mach, transcritical cylinder case with heat transfer. Is there any reason for that? Do you have new and/or improved solvers or discretization schemes?

See references about the OF1.7.1 and OF1.6-ext comparison:

If you have interest, my thesis can be downloaded from the link below:
