Abstract
In this article, flow rate in radial cooling ducts in a disc type winding model is characterized and measured using Particle Image Velocimetry (PIV). Good seeding density and reliable image calibration are essential to obtained accurate PIV velocity measurements. PIV measurement captured the existence of oil reverse flow and oil recirculation at duct entrances. A 3D flow was observed in radial cooling ducts under some OD cooling conditions
