TL;DR: In this paper, aperiodic multisampling technique with a hot wire in the clearance and with a high-response pressure sensor on the casing wall was used to obtain ensemble-averaged and phase-locked flow patterns in various tip clearances of two axial compressor rotors.

TL;DR: In this article, the effect of tip clearance on axial compressor rotor performance was investigated on the overall performance, work-done factor, blockage factor, and increases in displacement, momentum, and blade-force-deficit thicknesses of the casing wall boundary layer.

TL;DR: In this article, the authors investigated the three-dimensional structures of the vortical flow field in a propeller fan with a shroud covering only the rear region of its rotor tip and found that three vortex structures formed near the rotor tip: the tip vortex, the leading edge separation vortex, and the tip leakage vortex.

TL;DR: In this article, the authors investigated the effect of the breakdown of the tip leakage vortex in an axial compressor rotor at near-stall conditions and showed that the vortex breakdown causes significant changes in the nature of the leakage vortex, which result in the anomalous phenomena in the time-averaged flow fields near the tip at the nearstall conditions: no rolling-up of the leaky vortex downstream of the rotor, disappearance of the casing wall pressure trough corresponding to the leakage, large spread of the low-energy fluid accumulating on the pressure side, and large pressure fluctuation on

TL;DR: In this paper, a numerical simulation of hydrogen dispersion in a partially open space is presented, where the transient behavior of hydrogen and the process of accumulation in the space are discussed and the effects on the hydrogen concentration distribution of changing the vent positions, vent conditions and surrounding atmospheric currents are also shown.
