Hi there,
I have studeid the heat transfer tutorials (https://www.comsol.com/forum/thread/142322/joule-heating-in-large-electromagnet?last=2017-04-25T19:42:18Z) and (https://www.comsol.com/blogs/joule-heating-simulations-tutorial/) and tried to build my own thermal analysis of the mini solenoid for which I have a real model.
The magnetic field of the simulated model is very close (few % difference) to the real mock-up. However, I got huge disparity between the simulated and the measured tmperature. For the same input parameters the simulated model gives very high temperatures of 360 K at the point of contact on the side with the shorter neck, where in reality the measured temperature was 310-315K. I touched the core with bear hands and it felt warm, but not hot, so I am confident with the sensor read-out of ~310K.
I would like to ask for some help (maybe I have not complited the study of Heat Transfer in Solids sufficeintly) in order to decrease the difference gap between simulated and real measured temperature.
Looking forward to read from you.
Best Regards, Zoran
