EFFECT OF BACK PRESSURE ON RE-ENTRY TURBINE PERFORMANCE

Abstract

The intent was to investigate experimentally the influence of back pressure (Reynolds Number effect) on the stage performance and overall performance of a two stage re-entry type turbine, to analyze and correlate these data, where possible, with existing theories and to attempt a loss analysis which will separate the viscous losses from the non-viscous losses. For these tests, existing turbine hardware was to be used with only minor changes. The investigations were intended to be of exploratory nature registering the gross effects and main trends of the back pressure influence at supersonic as well as sonic approach velocities to the rotor.
