| Summary: | The performance and exit flow characteristics of two mixed-flow turbines have been
investigated under steady-state conditions. The two rotors differ mainly in their inlet angle
geometry, one has a nominal constant incidence (rotor B) and the other has a constant blade
angle (rotor C), but also in the number of blades. The results showed that the overall peak
efficiency of rotor C is higher than that of rotor B. Two different volutes were also used for
the tests, differing in their cross-sectional area, which confirm that the new larger area
volute turbine has a higher efficiency than the old one, particularly at lower speeds, and a
fairly uniform variation with velocity ratio. |
