Incremental Model Order Reduction of Smoothed‐Particle Hydrodynamic Simulations
International Journal for Numerical Methods in Fluids, Volume 97, Issue 12, Page 1571-1594, December 2025.The paper presents the development of an incremental singular value decomposition strategy for compressing time‐dependent particle simulation results, addressing gaps in the data matrices caused by temporally inactive particles. The approach reduces memory requirements by about 90%, increases the computational effort by about 10%, and preserves the ...

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

Energy Science &Engineering, Volume 13, Issue 2, Page 700-713, February 2025.Sediment erosion on Francis turbine components is visualized experimentally for two different operating points. The erosion rate of the Francis turbine runner is quantified during the operation. A benchmark test case is established that enables qualitative and quantitative validation of computational fluid dynamic simulations for erosion prediction ...

Performance Evaluation of Pelton Turbine: A Review
Hydro Nepal: Journal of Water, Energy and Environment, 2014 Earlier only experimental techniques were used to predict the performance of turbines. With advanced numerical techniques and increase in processing power of computers, Computational Fluid Dynamics (CFD) has emerged as an effective tool for the performance prediction of Pelton hydraulic turbine involving multi-fluid flow.
