results high temperature bar too high

[Anonymous]

hello, i've been trying to simulate conjugate heat transfer of an aluminium part with heat generation surrounded by an oil flow at given inlet temperature. the properties of oil were created and set to very with temperature. the flow is laminar and so this solver was set, together with Advection 2.

i have been noticing that throughout the simulation (and on finishing) the high temperature value in the results bar would be very large, way higher than the actual component temperature. the average part temperature seems to make sense and cannot find locations within the model that reach the temperatures shown at the upper end of the temperature scale. just wondering if this is a general problem or if it is a problem with my model. I am using CFD2014 and have installed SP2. help is appreciated. cheers, rob

hello CFD Support team,

just wondering if anyone can help with this one. is it a question of unchecking  the intelligent solution control and tightenning the pressure, velocity and temperature settings? i would appreciate your input. cheers, rob

Hi:

It is difficult to see if there are any problems with the setup. Can you post the supprt file? (Rename the "cfz" extension to "zip" before posting)

However, since you have a fluid with thermal conductivity significantly different from the solid, you should refine the mesh where they touch to account for sharp temperature variation in the vicinity.

Hope this helps.
