Experimental investigation on the stall inception of a counter-rotating compressor

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

For investigating the flow phenomena in the stall process of a counter-rotating compressor(CRC), static and dynamic experiment have been carried out on a low speed counterrotating compressor. Seven high response pressure sensors were mounted at the leading edge of rotor 1(R1) and rotor 2(R2) as well as at the outlet of R2 blade tip and root. Wavelet analysis and FFT transform was introduced to the post processing progress. According to the experimental results, the stall inception was found in the tip region of the second rotor. The rotating speed of stall cell in the compressor is about 35% of the rotor speed.
