Hello everyone, I was wondering about the convection phenomenon in the airgap of a permanent magnet machine. I found in the literature that we need to look for the Taylor number and then Nusselt number based on the flow type (speed) to find the thermal resistance in the airgap. But what about the boundary condition temperatures on the inner stator surface and outer rotor surface? Are they necessary to determine the temperature in the air gap using the LPTM model?
