evapPhaseChangeFOAM
 
2 Attachment(s)
i have developed a solver based on interFOAM, to solve energy equation and besides consider mass transfer between two phases, this solver works correctly for one dimensional case (stephan phase change problem)
but for two case studies, temperature at interface behaves strangely
now any suggestion, cooperation or idea will be helpful

P.S
developed files and case studies are available in attachment

some descriptions :) can be found here:

Hi.nimasam,im intersted in this problem,too.

have you solved this problem already?
Would you tell me the way to resolve this problem?

nimasam July 20, 2011 10:28

i solved the problem, if u like to received final code send me ur email;)

Hello Nimasam,
i have the same problem: phase change and evaporation due to heat transfer...
OF not have a default solver for this.
have you any suggestion for me to solve the problem in your solver?

Thank you

nimasam February 3, 2012 10:06

my solver solves evaporation with VOF interface tracking method, if you look at here:
http://www.cfd-online.com/Forums/blo...-openfoam.html
you will find some little description about how does it works and present situation of solver.

Thanks
 
Hi nimasam,
thanks for the reply.
do you share the correct solver code?
i have some problems with c++ programmation.

nimasam February 3, 2012 10:50

Hi
send me your email

antonessiu February 3, 2012 11:05

many tanks
 
thanks nimasam for your understanding...
my email is: seranto2001@yahoo.it

antonessiu February 4, 2012 11:25

Hello nimasam,
please re-send me the solver code,
the mail not arrived....
Thanks

Hi Nima Sam

I need to simulate boiling flow in OF but I could not find any solver for that. From this forum I found that you have developed your own code. Is it for boiling flow? May I use it?

Thanks

Hi, nimasam. I have always confused the implementation in VOF model. Can you send me your final code. My email is nygbook@gmail.com. Thank you!

Hi Nima Sam.

I'm also working on this topic and I would also be interested in having your source code, if possible, in order to test it on experimental data I have.

My email adress is julien.commanay at free.fr

Regards.

Dear Nima Sam,
Could you please send me the solver to zcarral@yahoo.es
Is it applied to bubble growing due to evaporation?
Thanks in advance

Dear Nima Sam,

I'm studying the instability of a boiling front and I'm really interested in the source code you developed. Could you please send me the OF solver ?
My email is psapin@imft.fr

Thanks,

Hi nimasam,
Will you please send me your code, my email: ahmmedshakil@hotmail.com

I would like to take a look at the code too ( albert.passalacqua@gmail.com)

PS. In the description you say you need level set. In reality, the level set alone would not be enough, due to conservation errors. There are combined level set - vof methods, and but frankly they become easily too complicated, they can lead to inconsistent representations, and and they are expensive (in some case the conservation problem is not resolved, and typically you need adaptive refinement anyways). I would suggest you take a look at the work of Popinet (Gerris code). They developed a geometric VOF with height functions/paraboloid interpolation to calculate the curvature. Combined with adaptive grid refinement it seems more promising than coupling level set and vof :-)

Best,

Hi nimasam,

neoxwolf@yandex.com

I would be pleased if you could send your code. I will compare with my experimental results.

thank you

sahas December 18, 2012 09:45

Hello, Nima Sam.

Would you be so kind to send your code to smirnovskysaha@gmail.com?
Thanks in advance!

Hi nimasam!

I had tried your code above in the attached file.
Actually because I am using of 2.1.x, so what I did is to read your code and apply all the changes by myself to interFoam. After some effort I compiled the solver successfully.
Unfortunately, I found when I run the StephanProblem, there were two issues:

1. temperature went extremely high near the interface, which caused extremely high velocity which is surely not correct.
2. pressure inside the domain went extremely high and cause some unrealistic velocity

would u please send me a copy of your final code? I am now stuck and don't know where was the problem.

my email:

houkensjtu@gmail.com

Thank u!
