Conclusion
Radial inflow turbines for turbocharging - Basic principles

A detailed description of the various components of centripetal turbines and their respective roles has been presented, with an emphasis on the specific adaptations developed for this type of machine. A comprehensive approach that defines the key parameters for achieving thermodynamic performance, as well as the technological adaptations required for their use, constitutes an initial approach to the active control of stator components specific to small supercharger turbines. Defining the various efficiency metrics allows the reader to clearly distinguish between the sources of losses, the modeling of which will be the subject of future articles. The fluid mechanics equations applied to stationary and moving components are reviewed, though no analytical or numerical solutions are proposed at this stage. Some of these solutions are developed in the article
