Hallo! I am a new OpenFoam-
I am a new OpenFoam-User and just doing my first steps.
Beside some other things I need to calculate the temperature distribution in a solid block, which consists of some different materials. The thermal conductivity of these materials depend on the temperature. Boundary conditions are mostly a temperature, a heat transfer coeffizient/ambient temperatur or heat flux. I would need the temperature in steady and unsteady state.
Up to now, I used Fluent/Gambit for those problems but in future we won't.
Creation of the mesh is no problem. But how can I setup this problem in OpenFoam? Do you know any tutorial or test case, which I can work thru to learn, how to solve such a problem?
Thanks in advance
Hello Michael Try the follo
Try the following link, you can also find a case file and required solver information here.
Just look through the case file and the solver.
Hi! As I understand it, he
As I understand it, he doesn't need the fluid part (except for the boundary conditions) - all parts are solid. So on one hand that solver would be too complex, on the other hand it is too simple because it still uses a constant thermal conductivity.
The "simplest" way would be to modify laplacianFoam to use a field instead of a constant for the "diffusion coefficient"/thermal conductivity.
Thanks for your replys. Be
Thanks for your replys.
Bernhard, you are right. My problem is "only" to calculate the temperature distribution within the solid (no fluid take part).
But, I have different solid materials, with different thermal conductivities and they are (in worst scenarios) all temperature dependent.
