Dear xyq102296

Do you know how to mesh the fluid flow over the fins?

[xyq102296]

Fins? THere are some tutorials about that.
But is this related to my problem?

It looks like the inlet conditions are different maybe. Like yours has a higher temperature at the core.

I can see from the thickness of the baffles/fins that the meshes are different. Have you checked for mesh independence in your solution?

Hello Michael,

THe inlet condition is same, I got the data of inlet speed and inlet temperature from the material.
How to check the mesh independence? I am new about this part.
Do you know how to define the inflation layer thickness, because I think I add the heat flux on the wall, so the first layer thickness is quite important, I don't how to define that number in my laminar flow model.

You should be asking your instructor these sorts of basic questions.

and for these picture, the model is 2D model, 5mm width and 2meters long, this picture is just the upper part of the model, the whole model looks like this

Can someone explain what sort of problem is this?
