Abstract

The focus of this paper is a computational fluid dynamics (CFD) analysis of the end winding region of a hydro generator as basis for development of correlations between the convective wall heat transfer coefficient (WHTC) and speed and flow rate parameters. These correlations are used as boundary conditions for thermal networks. Furthermore, there is also a focus on the influence of the numerical settings on the correlations. This work deals with a reduced numerical model which is designed to calculate a hydro generator fast and accurately by using a steady-state simulation with the mixing plane (MP) method.
