Proc. ASME. GT2022, Volume 1: Aircraft Engine; Ceramics and Ceramic Composites, V001T01A023, June 13–17, 2022
Paper No: GT2022-82347
... by introducing the air flow at hub region to the cooling fin. Therefore, in order to better improve the thermal performance of the cooling fin, an aerodynamic design of cooling fin is proposed in this paper for better thermal management of stator end-windings. Firstly, for a certain desired power output...
