Hello, I have to admit that I come from experience of Fluent, and am exploring Flow Simulation to simulate rotating flow for electric machine.
What I am trying to run heat transfer conjugated CFD analysis, it is to simulate an electric machine which will be cool down in the room by natural convection. Please take a look at my attached snapshot for your reference. Here is some basic summary to my settings:
1. internal flow. (I create a large case to put my machine there, thus there will be one surface P1 with pressure in, another surface P2 with pressure out, P1-P1 is a tiny bit....), Rotation is not turned on....
2. the machine's stator will be cooled down by forced convection through channels in its water jacket. thus I set up HTC and its bulk temp through flow simulation Outer wall B.C.
3. rotor assembly will rotate at a high RPM, thus some walls (as I marked out in yellow lines) will rotate. I set up its rotation B.C. through Real Wall B.C. specifying its rotating speed there. --> I am not sure if it is right
4. heat loss to all components, such as stator coppering winding, stator stack, rotor sleeve, rotor magnets, rotor hubs.
I am not sure if I set up all of B.C. all right and I feel like there might be something wrong, but not sure...
