Variable temperature on the wall as the Boundary Condition
I am a new user (I am petroleum engineer) of Fluent 6.3 and I am modeling a 2D Natural Convection in a vertical cylindrical annulus. I would like to put a linear decrease in temperature on the inner wall of the cylinder (for instance 50 oC at the top of the cylinder and decreases linearly to 40 oC, i.e. T(Z,R=Ri)=50-Z where 0<=Z<=1 m (Hieght) and Ri is radius of inner wall). Would you please tell me if this is possible to do in Fluent. If yes, how?
Many Thanks in Advance,
You can use a "udf" (user defined function) to specify temperature as a function of the location on the boundary surface using DEFINE_PROFILE.
Google "udf" and "DEFINE_PROFILE" for more info.
