A Review of Tip Clearance in Propeller, Pump and Turbine
Energies, 2018 Propellers, pumps, and turbines are widely applied in marine equipment, water systems, and hydropower stations. With the increasing demand for energy conservation and environmental protection, the high efficiency and the stable operation of pumps and ...

Journal of Physics: Conference Series, 2022 Abstract Due to the structural design requirements, tip leakage flow is a common phenomenon in the field of axial flow rotating machinery. The tip leakage flow interacts with the mainstream and induce complex tip leakage vortex. When the local pressure drops to the saturation pressure, cavitation may occur in flow passage and the vortex ...

Vibrations of an Axisymmetric Body in a Cavitating Leakage Flow
JSME international journal. Ser. C, Dynamics, control, robotics, design and manufacturing, 1991 This paper presents experimental studies of vibrations of an axisymmetric body in a cavitating leakage flow. The experimental passage is a narrow annular parallel passage. The effect on the characteristics of vibrations and the flow pattern in the passage were evaluated by changing the width of the passage, the downstream pressure and so forth.

Tip Leakage Flow in Axial Compressors [PDF]
Journal of Turbomachinery, 1990 Experimental measurements in a linear cascade with tip clearance are complemented by numerical solutions of the three-dimensional Navier–Stokes equations in an investigation of tip leakage flow. Measurements reveal that the clearance flow, which separates near the entry of the tip gap, remains unattached for the majority of the blade chord when the tip

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Tip-leakage-flow excited unsteadiness and associated control [PDF]
Tip leakage flow in turbomachinery inherently generates intense unsteady features, named self-excited unsteadiness, which significantly affects the operating stability, aerodynamic efficiency, and noise but has not been well understood.

Characterization of Unsteady Leakage Flow in an Axial Fan
International Journal of Turbomachinery, Propulsion and Power, 2023 The present work reports an experimental study of the leakage flow in a low-speed fan ring. Existing 2D Particle Image Velocimetry (PIV) measurements taken in a meridional plane in front of the rotor gap have been further processed and analyzed by means ...
