Solid–Liquid Flow Analysis of Francis‐99 Turbine Runner: Effects of Sediment Concentration
This study examines the behavior of solid–liquid two‐phase flow within the runner of the Francis‐99 turbine. Numerical simulations were carried out by Ansys Fluent software using the Mixture multiphase flow model along with the Realizable k‐ε turbulence ...

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

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
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 ...
