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

“…Calculations of the flow field and the mass flux distribution through the grooves were carried out in a sequence of four related cases Under an isothermal condition: (a) pumping flow, which is the self-generated flow resulted from the rotor pumping action; (b) mixing flow, which is the combination of the ventilating flow and pumping flow, under a constant density condition; (c) mixing flow, with density modeled by the ideal gas law; and (d) mixing flow, with different pressure differentials applied on the system. …”
