Optimized Mesh Zoning for Dam Bottom Outlet CFD Simulations Using Richardson Extrapolation and Grid Convergence Analysis

open access: yesEngineering Reports, Volume 8, Issue 6, June 2026.
A Richardson‐extrapolation–based mesh zoning framework is developed to optimize CFD simulation accuracy and computational efficiency in dam bottom outlet flows. Using six mesh scenarios and multi‐parameter convergence analysis (pressure, velocity, TKE), the method identifies an optimal fine‐resolution zone around the gate and progressively coarser ...

The Optimization of Savonius Helix Wind Turbine Cut-in Speed with the Variation of Blades-twist Rotor and Number of Blades

open access: yesJIPTEK: Jurnal Ilmiah Pendidikan Teknik dan Kejuruan, 2023
Wind turbines are typically classified as Horizontal Axis Wind Turbines (HAWT) or Vertical Axis Wind Turbines (VAWT). VAWT has a superior ability to accelerate from rest to rotation than HAWT, allowing it to rotate the rotor even when the wind speed is ...

Impacts of Blade Camber on Cross‐Flow Turbine Performance and Loading

open access: yesWind Energy, Volume 29, Issue 5, May 2026.
ABSTRACT Cross‐flow turbines show promise for renewable energy generation from wind and tidal sources. The rotating reference frame of cross‐flow turbine blades results in virtual camber and incidence due to streamline curvature, altering the lift, drag, and pitching moment of the blades. Adding geometric camber is therefore likely to alter performance
