Default Heat sink with forced convection problem
Posts: n/a

I am a new user to fluent. Can any one tell me the steps involved in modeling a heat sink in Gambit and solving it for forced convection problem (air impingement). I am having little problem in understanding the concept. Is there any tutorial which solves the above problem? I would really appreciate your help.

Thank you, prasad

when it comes to modeling the heatsink, icepak is better than fluent

Dear Caesar

Nowadays, I am doing a research about heatsink using Fluent. But, I have some problems. Actually, , the numerical data using fluent is quite different from experimental data. (my model is laminar flow.)

Do you have that kinds of experience with fluent?

Could you explain what aspect icepack is better than flunt?

Thank you inadvance!!

I am also a freshman in this field,but I have learned icepak. it is a professional software in resolving the electronic heat disspersing. Many models including heatsinks can be constructed easily in it. And it needs not many knowlege of CFD. By the way it also use fluent as solver.

i'm working on simulation of mixed turbulent convection in a rectangular horizontal channel were I have heat sources like electronic compounents anyone can help me to simulate that problem using any code
I have nummerical results to valid my results
waiting ur answers thx.

Hi Prasad,

As per your post , i feel that Icepak might be more appropreate tool for you to model a heat sink. because ... Unlike gambit, icepak is a specialised tool for electronic cooling. It has some default components like heatsinks, grilles and openings, different geometries inbuilt in it.. the thing you need to do is just to select the desiered component and resize it a per your requirement.
This doesn't take much of your effort.. and a little knowledge of fluid dynamics and heat transfer are sufficiet for your study... ALL THE BEST...

Hi Caesar,

Fluent is just a solver... In that we can siply go for case setup and launch the run.. Where as icepak has got some additional capabilities like modeling, meshing , case setup etc... apart from that icepak also uses fluent as its solver...

You commented that the simulation results are deviating from the numerical data.. i think there might be a possibility of a wrong case setup usage.... try checking the case setup.... For Heat sink simulation, i would prefer to suggest for using Icepak....

Hi Iyes,

Frankly speaking i dont have enough knowledge about the code... But as per your description, i understood that you want to simulate a horizantal channel with turbulent flow regime and forced convection ... including some electronic components in your simulation... for this kind of applications, Icepak is a very useful tool.. it has got very user friendly GUI environment... helps the new user also to get accustomed easily.. ALL THE BEST....

Best Regards,
