temperature inlet bondary condition
My inlet BC type in FLUENT is "pressure inlet", and I want to use the BC as below : dT/dX = 0 where T is temperature and X is normal to the inlet bondary, and my case is 2-D. By reading the FLUENT guideline, I think this BC may use the UDF code to edit this condition, but I don't know how to solve the temperature gradient by using the code, can anyone help me? Thank you very much .
First of all
Don't Thrust me, because I am a newbie :cool:
I think you can use "pressure inlet" when du/dx=0..
or... I don't know(sorry:rolleyes:) mabye UDF can save you.
you don't mean adibatic wall, right?
My original inlet BC is : n●grad(T) = 0 where n is normal direction vector and grad means gradient. So it can be simplified to dT/dX = 0.This condition means I neglect the inlet thermal conduction effect.
