An Investigation of the Limit Cutting Depth of Robotic Milling Based on Response Surface Methodology

open access: yesJournal of Engineering, Volume 2026, Issue 1, 2026.
Robotic milling technology has been gradually applied to the repair of water turbines due to its advantages of high flexibility and low cost. However, the weak rigidity of the serial robot makes the milling process more prone to vibration and chatter. This paper investigates the effects of tool overhang length, spindle inclination angle, and feed rate ...

Effect of Guide Vane Pitch Circle Diameter on Pressure Fluctuation in Vaneless Zone of Francis Turbine

open access: yesJournal of Applied Fluid Mechanics, 2020
In a Francis turbine, the guide vanes are arranged in the direction of flow behind the stay vanes. And as it is generally believed that the outlet angle of water after it flows through the spiral case and stay vanes is fixed, the flow and flow ...

An Experimental Test of Hydropower Entrainment Risk for Subadult Sea‐Run Brown Trout (Aka Blenkje; Salmo trutta)

open access: yesEcohydrology, Volume 18, Issue 8, December 2025.
ABSTRACT Brown trout play an important role in the northeastern Atlantic aquatic ecosystems, moving between freshwater and marine environments to maximize fitness across their lives. The blenkje (aka finnock) is a life stage of migratory brown trout that returns to freshwater after its first summer migration to sea without maturing.

Design optimization method for Francis turbine

open access: yesIOP Conference Series: Earth and Environmental Science, 2014
This paper presents a design optimization system coupled CFD. Optimization algorithm of the system employs particle swarm optimization (PSO). Blade shape design is carried out in one kind of NURBS curve defined by a series of control points. The system was applied for designing the stationary vanes and the runner of higher specific speed francis ...
