Solid–Liquid Flow Analysis of Francis‐99 Turbine Runner: Effects of Sediment Concentration

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT 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 model to analyze the solid–liquid two‐phase flow in the turbine runner.
