Abstract

The steady and unsteady performance of two mixed-flow turbocharger turbine rotors has been investigated. These rotors differ mainly in their inlet blade angle geometry; one has a constant blade angle (rotor A) and the other a notionally constant incidence angle (rotor B). The results indicate that the constant blade inlet angle design offers improved efficiency characteristics over the constant incidence one with total-to-static efficiency at the design point ranging between 0.7 and 0.76. A detailed assessment of the influence of volute geometry on the turbine performance has been carried out, which confirmed that the geometry of volute plays a critical role in the overall performance of a turbine. The unsteady performance tests have indicated a substantial deviation from the performance and flow characteristics of equivalent steady-state tests, which is quantified and discussed.
