How to model fluid flow pass over fin
Dear All

Could somebody give me your suggestion about simulation heat transfer flow pass over the fin by using ANSYS Fluid Flow(Fluent) (I'd like to see the outlet pressure drop, heat transfer of the fin). I already made fin but I have no Idea how to model fluid flow which pass over the fin(I use Ansys flow DesignModeler ), how to set the inlet condition on the part. I pretty new about Ansys so if you guys have the tutorial could you give me about this ??

sincerely your

You need to create an enclosure around the fin that the mesher can fill with mesh to represent the fluid...

If you put both bodies (the fin and the enclosure) into the same part, you will have a multibody part that will mesh with conformal nodes... Then just run tetra prism on it (prism on the fluids side, but maybe also on the solid side)...

I recall some packaged demos about this (a heat sink with a fan in a pc tower), but I just did a quick search and didn't find them. I am sure I have it on a CD somewhere but I am mid-move and have not unpacked my office yet. You may find the "killer demo" on the customer portal.

Best regards,
