A One-dimensional Analysis and Performance Prediction of Subsonic Radial Turbines

Abstract

A one-dimensional analysis of subsonic radial turbines in terms of non-dimensional velocity λis developed introducing a new incidence loss model. Based on this theory a performance prediction of radial turbine of a tip diameter d₃=228 mm is conducted. The predicted performance is compared with experimental results, and is considered to be of a sufficiently good coincidence. Comparison with incidence loss models, one due to Wallace and the other to NASA, is also presented.
