Experimental assessment of a fully predictive CFD approach, for flow of cooling air in an electric generator

Moradnia, Pirooz; Chernoray, Valery; Nilsson, Håkan - In: Applied Energy 124 (2014) C, pp. 223-230

A fully predictive computational fluid dynamics approach is assessed for the flow of cooling air in an axially cooled electric generator. The flow is driven solely by the rotation of the rotor, as in the real application. A part of the space outside the generator is included in the computational...
