摘要：

The heat transfer coefficients in the ventilation channels of a turbogenerator stator of new construction, containing slot-shaped axial channels in the teeth, are investigated. Experiments are carried out on a full-scale physical model with air cooling and on a turbogenerator with hydrogen cooling. In the latter case, active heat-transfer sensors, simulating the slot-shaped channels, are built in to the circulation circuit of the cooling gas of a commercial turbogenerator with hydrogen cooling when it was undergoing bench testing. The results of the experiments can be used when designing high-power turbogenerators with total gas cooling. © 2014, Springer Science+Business Media New York.
