Periodic Unsteadiness of Compressor Tip Clearance Vortex
Volume 6: Turbo Expo 2004, 2004Natural and forced responses of the tip clearance vortex are measured in a linear compressor cascade to characterize periodic unsteadiness of the tip clearance vortex. There exists a natural frequency at which the tip clearance vortex is the most receptive to external forcing, thus resulting in mixing enhancement and flow blockage reduction. A physical

High-Speed, capacitance-based tip clearance sensing
2013 IEEE Aerospace Conference, 2013This paper discusses recent advances in tip clearance measurement systems for turbine engines using capacitive probes. Real time measurements of individual blade pulses are generated using wideband signal processing providing 3 dB bandwidths of typically 5 MHz.

Investigation of Compressor Tip Clearance Flow Structure
Volume 7: Turbomachinery, Parts A, B, and C, 2010By the use of decomposition for the three-dimensional flow field in compressors into independent through flow and cross flow as first proposed by Chen et al., the tip gap flow structure for different tip gap heights and boundary conditions is examined.

SHROUDED PROPELLER INVESTIGATIONS: PROPELLER TIP CLEARANCE EFFECTS
1961Abstract : Wind tunnel tests were conducted on a shrouded propeller model in which the propeller diameter was varied for the purpose of measuring the effects of tip to shroud clearance. The basic model tested contained a four-bladed variable pitch propeller operating within a 0.50 chord/diameter ratio shroud. To assist in studying the effect of annulus
