Heat Transfer Coefficient
I just installed openFOAM, so sorry if the question sounds stupid, but how do I set a heat transfer coefficient and prescribed heat flux in the laplacian solver?
I have this routine in fluent which I just simulate the solid with standard heat transfer conditions (heat tranfer coefficient, fixed temperature and prescribed heat flux) and I want to try to port it to openFOAM. Later I will need to run a optimizer and it looks like openFOAM can be reasonably faster. Any suggestion? Thanks |
You can set a fixed heat flux by setting a temperature gradient BC. Look in /0/T
There is a similar procedure for the fixed temperature. type gradient value uniform 8 (the gradient value) type fixedValue value uniform 400 (temperature value) |
Thank you, but how do I set the heat transfer coefficient? and the reference temperature?
|
I don't know an easy way to set that up.
|
Thats something unexpected =O
can you give me just give me some start instructions about the hard way? |
I would say that you have to implement a new boundary condition. I don't think this type of BC exists as of yet. However, I would search the forum thoroughly before doing anything else.
