I am not sure if I am doing this right, especially because my analytical solution is quite different, so could you please help me to get this simulated correctly?
I am trying to model a copper canal of an electrical machine which is directly cooled by a fluid. For a first try I used 2 copper canals (3mmx10mm) with a source term (fitting to the power dissipation through the current with J=40A/mm² and a filling factor of 0.6) and a cooling canal (2,4mmx10mm) in between. The length of the system is 170mm.
For the cooling fluid I took an oil-like fluid with a starting temperature of 120°=393.15K. I used different velocities from 1 m/s to 5m/s in the cooling canal.
The result is, that the copper has a difference of temperatures in those 170mm of about 3,7 K with 1m/s and about 1,8K with v=2m/s. The fluid has differences in temperature of 3K with 1m/s and 1,4K with 2m/s .November 25, 2020 at 2:22 pmRobForum ModeratorYou may want to look at thin walls to add the insulation layer. Check mesh resolution, convergence and materials. The images look OK, but the detail will be critical. nViewing 1 reply thread
