  • Types of Hydropower Turbines | Department of Energy

    REACTION TURBINE. A reaction turbine develops power from the combined action of pressure and moving water. The runner is placed directly in the water stream flowing over the blades rather than striking each individually. Reaction turbines are generally used for sites with lower head and higher flows than compared with the impulse turbines.

    A variable axis turbine may include ple nested rotatable rotor assemblies. The turbine may be self-starting in slow fluid conditions while simultaneously self-limiting in fast fluid conditions. The turbine may provide omni-directional energy recovery and be self-balancing. The nested rotatable rotor assemblies may be configured to rotate independently of each other, but along the same ...

  • Aerodynamic Performance of Novel Lightweight Turbine Blade ...

    The primary contribution of this research is to clarify the aerodynamic performance of a novel lightweight turbine blade with internal cooling passage and external film cooling, which is invented aiming at drastic weight reduction of a cooled blade.

  • Novel cooling strategies for improved protection of gas ...

    Advanced gas turbines are operating at peak turbine inlet temperature (as high as 1700ºC), which are well beyond the maximum endurable temperature of blade. Figure 2 shows the variation of turbine entry temperature over recent years, collected in Han et al.[1]. Over the last 40 years, it is clear that the inlet temperature was found to increase

    Apr 06, 2013 · Of course the TET is bounded by the metallurgy of the turbine blade materials. The TET has increased from around 800°C in 1940 to 1500°C in the 1994 Rolls-Royce Trent engine. This development has in part been due to better materials but more importantly through channelling of cold compressor air to cool the turbine blades.
