Application of a compliant foil bearing for the thrust force estimation in the single stage radial blower

open access: yesOpen Engineering, 2015
The paper presents the application of a compliant foil bearing for estimation of the thrust force in a single stage radial blower under operational conditions. The bump foil of the thrust bearing behaves as a nonlinear spring. The knowledge of the spring

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

open access: yesEnergy Science &Engineering, Volume 13, Issue 8, Page 4131-4142, August 2025.
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.
