This comes from a stress guy, therefore don't laugh at me !
I am presently working on the thermal analysis involving an electric motor whereas a heat source is applied to the windings, magnets and core. I have modelled a 3D sector including the air gap with SOLID70 elements. I have done this since assessing the convection coefficient for the gap isn't straight forward, therefore I'd like to replace the convection effect by an equivalent conduction in the solid representing the gap.
Do I have to consider CFD for such a problem, or can I get away with proper assumptions ? If not, I guess FLOTRAN would not do the trick since I am faced with a rotating frame of reference...
Any comments or hints on how to model the gap would greatly be appreciated ?
Best regards.
