Transient Conjugate Heat Transfer
 
Hi,

I am doing a transient conjugate heat transfer to find the surface temperature across an insulated cylindrical duct. The properties of the insulation material are cp = 1046 j/kg.K, k= 0.08, density=850kg/m3. inlet temp = 913K

The transient temperature response for such a model is too slow and it actualy happens only after a time delay of 200 sec. I am curious to know whethere anyone has faced similar kind of situation.

I wud appreciate your help on this

pls try with adaptive time step methodology....

Further to what Jay has mentioned, about correctness of the result you have obtained, it doesn't seem wrong at all to find that it takes around 3 (or 3+) minutes for the temperature profile to develop fully across the insulation. You can very much conduct the experiment, if it is possible, to validate your result. Best luck.
