EFFECT OF NOZZLE GEOMETRY ON OFF-DESIGN PERFORMANCE OF PARTIAL ADMISSION IMPULSE TURBINES

Abstract

The object of the study was to obtain information to improve the off- design performance of supersonic turbine nozzles. The scope of study entailed a literature search, a theoretical analysis, and an experimental program. A total of 60 reports were reviewed during the literature search; comments on each are presented. The theoretical study shows that off-design performance can be successfully predicted. The experimental information obtained supports this theory. The ratio of specific heats of the working fluid was found to be influential on the off-design performance. Further study is required, however, before definite conclusions may be reached. (Author)
