... and reattachment points are fixed at the upstream and downstream corners of the block. The local Reynolds number, based on the Helmholtz–Smoluchowski velocity, increases with the rise of ζ , and hence the vortex strength increases. We expect that the strength of the vortex must depend on the block height...

... over the third stage rotor have been acquired with high-frequency-response pressure transducers. Also, tip vortex strength and trajectory have been estimated from the casing pressure fluctuations which have been obtained simultaneously from various axial locations. As flow coefficient decreases, tip...
