Tip clearance flows in axial flow compressors and pumps

Tip clearance flows in axial flow compressors and pumps

Flow in the clearance at the rotor blade tips of axial flow compressors and pumps was studied experimentally and theoretically with particular attention to losses. It is shown that losses due to blade tip clearances can be evaluated in a simple manner for high efficiency turbomachines. A vortex sh...
