Abstract
This study considers the turbulent heat transfer in the air-gap of an enclosed rotor-stator system subjected to the prescribed wall temperature. The aim is to improve the thermal performance of this discoidal system, and to do so a new cooling solution is investigated with holes introduced in the rotor. Multiple reference frame (MRF) and sliding mesh (SM) techniques are employed to model the rotor-stator interaction. The heat transfer rate and flow characteristics were calculated for the rotational Reynolds number 2.50x10(4) <= Re=Omega R-2/upsilon <= 2.50x10(5) and the air-gap ratio 0.00667 <= G = s/R <= 0.02667. The results reveal that the addition of the holes in the rotor is advantageous for the heat transfer and it can increase the heat transfer rate in the stator up to 25%.
