UDF and UDM for heat transfer coeff. calculation
 
1 Attachment(s)
Hello,

First of all, I have to say that Im totally new to UDF- programming. Ive read several threads about this topic, but didnt find anything suitable.

My problem is as follows.

I want to calculate the heat transfer coefficient between a condenser wall (with fixed temperature) and the surrounding water.

My plan for writing my own udf is:

read the specific heat flux q'' and temperature at the adjacent wall and read a characteristic fluid temperature somewhere near this wall.

Then I would calculate the corresponding heat transfer coefficient for each cell.

Following I would like to display the calculated results in a contour plot or something similar. I think this would be possible with a udm?!

Attached you can see my geometry. It is a cyclic periodic 3D mesh.

If somebody could be so nice and give me a small hint, how to do this, I would appreciate it very much.

Thanks in Advance,

christoph
