Determination of Discharge and Thrust Coefficients of a Choked ASME nozzle from Exit Flow Surveys (Additional Test)

Abstract

This study determined the discharge and velocity coefficients of an ASME long radius metering nozzle. Previous tests of this nozzle had been conducted with an exhauster system which permitted operation at variable pressure ratio while keeping the Reynolds number constant. These additional tests were conducted to determine: (1) Whether the presence of the exhauster duct or the survey rake significantly affected the integrated data; (2) The effect of further changes of operating pressure ratio in the lower ranges of pressure ratio; and (3) The effect of decreasing the Reynolds number.
