Experimental Investigation of the Flow Field in a Multistage Axial Flow Compressor [PDF]
Volume 1: Turbomachinery, 1994 The nature of the flow field in a three stage axial flow compressor, including a detailed survey at the exit of an embedded stator as well as the overall performance of the compressor is presented and interpreted in this paper. The measurements include area traverse of a miniature five hole probe (1.07 mm dia) downstream of stator 2, radial traverses ...
