Flow behaviors in a Kaplan turbine runner with different tip clearances

open access: yesAdvances in Mechanical Engineering, 2021
Tip clearance between the runner blade tip and shroud in a Kaplan turbine is inevitable, and the tip leakage flow (TLF) and tip leakage vortex (TLV) induced by the tip clearance have a considerable effect on the flow behaviors.

Prediction of the Influence of Runner Tip Clearance on the Performance of Tubular Turbine

open access: yesJournal of Marine Science and Engineering, 2022
Tubular turbine is a type of turbine with low-head. Due to the fact that the runner of a tubular turbine is of axial-flow type, there will be a certain width of blade tip between the blade and the chamber.

Laser-Optical Blade Tip Clearance Measurement System [PDF]

open access: yesJournal of Engineering for Power, 1981
The need for blade tip clearance instrumentation has been intensified recently by advances in technology of gas turbine engines. A new laser-optical measurement system has been developed to measure single blade tip clearances and average blade tip clearances between a rotor and its gas path seal in rotating component rigs and complete engines.

Dual-Laser Probe Measurement of Blade-Tip Clearance [PDF]

open access: yesVolume 5: Manufacturing Materials and Metallurgy; Ceramics; Structures and Dynamics; Controls, Diagnostics and Instrumentation; Education, 1998
This paper describes two dual-laser probe integrated fiber optic systems for measuring blade tip clearance in rotating turbomachinery. The probes are nearly flush with the casing inner lining resulting in minimal flow disturbance. The two probes are closely spaced in a circumferential plane and are slanted at an angle relative to each other so that the
