An Experimental and Analytical Study of Tip Clearance Effects in Axial Flow Compressors

摘要

An analytical and experimental study of the performance changes and flow effects ofrotor tip clearance variation in axial flow compressors is presented. The analysesdemonstrate that previously unrecognized loss characteristics and flow behavior trendscan be identified in a wide range of published tests of clearance effects. Theperformance and flow data are correlated at constant power conditions or nondimensionally in terms of the test compressor's geometry and wall flow conditions toobserve the trends.
