Radially resolved measurement of stator heat transfer in a rotor-stator disc system

Abstract:

This paper describes a new experimental method for measuring stator heat transfer in a rotor-stator disc system using an electrical heater array. The system is partially blocked at the periphery, with radial outflow of rotor-pumped air from an inlet at stator centre. The aim is to improve thermal performance prediction for air-cooled disc type electrical machines. Local Nusselt numbers were measured for 0.6 < r / R < 1 at three non-dimensional gap ratios G = g / R = (0.0106, 0.0212, 0.0...
