WebCooled radial-inflow turbines are of interest for small (less than 2.27kg/s or 5 pps) gas turbine engines. However, the technology of cooling radial-inflow turbines, particularly rotors, is in a rudimentary state. The purpose of this program was to advance that technology. As a focal point for the work effort, A radial turbine is a turbine in which the flow of the working fluid is radial to the shaft. The difference between axial and radial turbines consists in the way the fluid flows through the components (compressor and turbine). Whereas for an axial turbine the rotor is 'impacted' by the fluid flow, for a radial turbine, the flow is … See more Compared to an axial flow turbine, a radial turbine can employ a relatively higher pressure ratio (≈4) per stage with lower flow rates. Thus these machines fall in the lower specific speed and power ranges. For high … See more The stagnation state of the gas at the nozzle entry is represented by point 01. The gas expands adiabatically in the nozzles from a pressure p1 to p2 with an increase in its … See more The total-to-static efficiency is based on this value of work. See more The stage work is less than the isentropic stage enthalpy drop on account of aerodynamic losses in the stage. The actual output at the turbine shaft is equal to the stage work minus the losses due to rotor disc and bearing friction. 1.
