how to modeling evapourating in pipe flow?
 
I have heard that fluent can not model evapourating.Is this true?if not ,help me please,thanks a lot

Re: how to modeling evapourating in pipe flow?
 
You can implement a model for evaporating with udf. You will need to write at least two equations for mass and heat transfer between you phases. Look at the tutorial "horizontal film boiling" at http://www.learningcfd.com/login/flu...ials/index.htm for more details.

good luck

Re: how to modeling evapourating in pipe flow?
 
when evapourating happens,in pipe flow, the flow is two-phase flow. And i do not have username and password. Could send me some material to me ? Thanks a lot! wwwsailor@126.com

Dear Mehdi Ghoddosy, Thank you for your help! Since I have no experience of simulating evapourating in pipe flow, still I need the source file (boiling.c).Could you send the file to me?Thanks a lot!

Re: how to modeling evapourating in pipe flow?
 
Dear Joey:Sure, I will send it.(mesh + boiling.c)

same problem
 
I want to simulate water evaporation from water pool. I need some information to simulate multhiphase flow. Could you send me tutorial if you have.
thanks alot.

Dear Mehdi Ghoddosy,

i 'm an undergrad, i'm doing simulation of heat pipe for the evaporation zone for my FYP. So it include boiling. Kindly ask that could you email to me the boiling tutorial that you have receive previously?? i dun have the username and password for the fluent tutorial....
.

I 'm really in desperate stage. Appreciate alot for ur help!!! Thanks in advance if u can email to danieleylai@hotmail.com. Thanks alot!!!:)

hi...i do have a problem with evaporation , condensation...kindly send the tutorial to my mail id here.senthil@gmail.com

imnull January 17, 2012 20:52

I need it as well gent!
pls email me the one to djurinskym@hotmail.com
thanx in advance

Look at the dates, guys/girls. You are requesting a tutorial that is nine years old. You can better look in the Fluent help.

Furthermore, if you need a username and password to access files, and you don't have those, it has a reason: probably this is to protect the copyrights. If you obtaining these protected files from a different source, you are (in most countries) breaking copyright laws, and could be fined.

udf and mesh
 
Hi, can you please send me the boiling.c and mesh files? I'm in desperate need for that.
My email is zhangxiaobinghust@gmail.com
Many thanks!

xiaobingwill April 25, 2014 00:47

Can you send me the two files(mesh + boiling.c) as well? Thanks
my email is zhangxiaobinghust@gmail.com

Modelling flow boiling in fluent
 
Hey guys,

I have been trying to simulate flow boiling process of water in fluent. But I have been facing a lot of problems of convergence. The calculation runs smoothly (converges) until some time and when it encounters the vapor that has been formed, the momentum and continuity values start diverging. I have tried changing the mesh size and time-step. The problem with going for too low time step is that it will take years for the calculation to get completed and with a larger mesh size, visualization of the bubbles is not possible.

Can anyone point out the problem and suggest a viable solution?

hi Joey,
i have the same problem but with condensation...
can someone send the tutorial to my mail id?:
jeffassouke@gmail.com.
Or can someone just post the link for this tutorial.

Hi Ghoddosy am trying to model subcooled flow boiling without using udf.. so far i haven't been able to successfully create the boiling phenomenon... the liquid flashes at exit instead of boiling gradually... can you help me with this.. tutorials or materials or advices of any form would be helpful..
