Hi everyone, I'm new to OpenFOAM but have Fluent experience. I'm choosing a package to use at work, but am unsure whether OpenFOAM is able to solve the case I need.

Specifically, I have a bluff body, Re = 33k. With Fluent, I found best results using an RSM turbulence model, so hope to use it here. An added complication now, is thermal effects. I want to simulate the heat transfer from the flow into the body, and from the body into the flow, at the same time as the turbulence calculations.
The temperature distribution throughout the body
is also required.

Is this possible?

Best regards,

Mark.

Um, anybody know? A yes / no is enough; I'll investigate from there. It looks to me like it will do it, but some verification would be nice....

BR,

Mark.

Well, it appears that to solve thermal transport with incompressible, laminar flow with an unsteady solution, requires copying, changing / adding to the solved equation by editing the code, and recompiling; detailed at

http://openfoamwiki.net/index.php/Ho...ure_to_icoFoam

So, I'm wondering, how complicated is it to generate the temperatures in a solid body, in a turbulent flow. Possibly, very?!

Comments, anyone?

Isn't chtMultiRegionFoam solver designed to perform such cases ? : http://opencfd.co.uk/openfoam/doc/st...l#x13-880003.5

The only point to be discussed concerns the possibility to use a RSM model since it does not to be available in the RASproperties from the tutorial.

and

and was getting worried. I'll explore your suggestion. As far as the RSM model is concerned, it is of importance, I'm afraid. Still, things look better, already! Thanks....

BR,

Hello Mark,
I think you will find this discussion also interesting: conjugate heat transfer

I hope it will be helpful,
Dragos

Hi Dragos,

Wonderful link, and very interesting! I am going to recommend OpenFOAM at work, and start the installation.

BR,

Mark.
