Numerical Analysis of Rotating Pumping Flows in Inter-Coil Rotor Cavities and Short Cooling Grooves of a Generator by Wei Tong

“…Results show that the pumping effect is strong enough to generate the cooling flow for rotor winding cooling. Therefore, for small- or mid-size generators ventilation fans may be eliminated. …”

Investigation on the influencing mechanism and quantitative evaluation of stirred heat effect in high-speed mechanical seals by Xuezhong Ma, Xiaoxin Xiao

“…Firstly, in terms of cooling flow, the cold fluid flow from sealed chamber into sealing gap is impeded by the high-speed shear effect of rotor outer sidewall, and a larger vortex namely a flow dead zone is generated at the spiral groove root due to the turbulent flow regime, which significantly impede the cooling level of fluid film and sealing end faces. …”
