How can a heat pipe in gambit model?

Whether it is possible or should be done programming?

Hi maxy,

I do not understand your question - could you pleeeeeeeeeease elaborate?

You are in the Fluent part of the forum, if you want to ask about Gambit you should post in the appropriate section.

hi

obvious I mean.

i Want model heat pipe (Shape above).i want make model by gambit.

Is that possible?

 Marion November 7, 2012 08:56

Yes it is possible to create the meshing in Gambit.

how?

because is difficult.

can you create?

 Marion November 7, 2012 11:20

Maybe I haven't understood your problem, but the geometry looks fairly simple to me.
Only pipes, you may even do that in 2D-axi.
Have you ever used Gambit?
But no, I won't create it for you if that's what you are asking.

i work with gambit and fluent.

i am asking but i don't say create for me.

my Request is Guidance for Performance that project.

Also,My English is not good but I understand what you say to me.

hi
yes it is possible.doesnt seem to be hard.you can model it in 2D or 3D but 2D is easier and th equations can be solved and converged faster in Fluent than 3D since less meshes are required in 2D.
GOOD LUCK

OK, sorry for misunderstanding your request.

I would model it using 2D-axisymmetric (you model only a slice of the system), don't forget that the Axis should be the X axis and that you have to put your mesh in the X-Y plane (Y>0).

You can mesh the solid parts with gambit, and then define them as solid in Fluent.
then for the multiple inlets and outlets it is also possible to define that in gambit/fluent.

maxy,

Here is a quick example in Gambit - I used ramdom dimensions, but for me in 2D it's only rectangles.

You have to define the edge on the X axis as "axis".

Hope this helps,

Marion.

You said that this example is very basic.

Look into the tube?

1. Has two phases.
2. A wick between steam and water are thrilled. Kind of metal
3. Heating tube is first.
4. Was cooling in the end.

Can you explain more?

I replied to you regarding the meshing part of your project (modelling this in Gambit) - it is possible, and quite easy.
For the setup in Fluent, well I am not a Heat pipe expert and I'm afraid I cannot help you further.
