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

Time-of-flight tip-clearance measurements [PDF]
35th Joint Propulsion Conference and Exhibit, 1999 In this paper a time-of-flight probe system incorporating the two integrated fiber optic probes which are tilted equally relative to the probe holder centerline, is applied for the first time to measure the tip clearance of an advanced fan prototype. Tip clearance is largely independent of the signal amplitude and it relies on timing measurement.

Numerical simulation of tip clearance impact on a pumpjet propulsor
International Journal of Naval Architecture and Ocean Engineering, 2016 Numerical simulation based on the Reynolds Averaged Navier–Stokes (RANS) Computational Fluid Dynamics (CFD) method had been carried out with the commercial code ANSYS CFX. The structured grid and SST k–ω turbulence model had been adopted.
