EFFECT OF REYNOLDS NUMBER ON TURBINE PERFORMANCE AT VARIOUS MACH NUMBERS.

Abstract

An analytical and experimental program was conducted to investigate the inter-relationship of Reynolds number (Re) and Mach number (Mn) effect (on the efficiency of axial impulse turbines) in the Re range of from 800 to 10,000 and the Mn range of from 1.15 to 3.0. The optimum pressure split of two-stage re-entry turbines operating in the Re and Mn ranges was determined. The performance potential of twostage re-entry turbines was formulated. The Re effect on three-dimensional flow patterns such as occur in the Silvern tangential flow turbine was investigated. Preliminary trends of Re and Mn inter-relationship inherent in tangential flow turbines were determined.
