Wall boundary condition (heat transfer)
 
Hello everyone

I have faced some problems about setting the Wall Boundary Condition. In my problem, I would like to set up a wall boundary which it's surface temperature, heat flux and convective coefficient are not constant and are affected by the surrounding environment. For instance, the temperature, heat flux and convective coefficient would be affected by the temperature of the fluid, the radiantion from other walls, etc.

However, I don't know how to set up a wall like this in fluent. Would anyone can help me to solve this problem? Thank you very much!

hi Arnold

I feel u need to use user defined functions udfs for the case you are considering

Please go through the udf manual of FLUENT if you are using FLUENT

They will be similar to C codes bye Ravi Kiran

Create the wall. Set the BC to coupled.
