Default lubrification oil model

hello anyone,

I'm trying simulate a small oil gap, between a rotor (rotation wall) and a stator (static wall) to steem the power losses due to viscous shear-stress. I know it's all about Couette-Taylor Theory and I was wondering if someone else could give some advises. I did a 20 degree model in Gambit and on the rotor wall I set as a symmetric condition. The stator wall as a wall and on the gap wall I set as periodic condition. Is it correct? Couette-Taylor Theory gives me Turbulent and an Instable Flow, so a K-E turbulent model have to be applied. How about the B.C in Fluent? There is anyway to simulate conduction in both sides using the heat generated by this viscous dissipation at the same time? Thanks.
