The effect of reynolds number on the performance of a single-stage compressor

Abstract

In a preliminary report a description has been given of some tests on the effect of Reynolds number on the static-pressure rise through a single-stage axial-flow compressor. The work has since been extended and the full performance data of the compressor obtained over a wide Reynolds-number range. This report presents a comprehensive review of the results obtained in the complete test series. The tests were carried out in the National Gas Turbine Establishment Variable-Density Return-Flow Rig. As description of the rig is beyond the scope of this report, a complete description of the rig and the operating technique will be issued as a separate report.
