Abstract:Efficient and compact axial compressors are currently undergoing rapid development for use in micro-cooling systems and small-scale vehicles. Limited experimental work concentrates on the inner flow field of the compressors working at such low Reynolds numbers (Re ~ 104). This study examines the vortical structures and the resulting turbulence production in the transitional flow over a C4 compressor blade at a Reynolds number Re of 24000, with a specific focus on the impact of tip clearance.
