Multigrid optimization for space-time discontinuous Galerkin discretizations of advection dominated flows [PDF]

, 2010
The goal of this research is to optimize multigrid methods for higher order accurate space-time discontinuous Galerkin discretizations. The main analysis tool is discrete Fourier analysis of two- and three-level multigrid algorithms.

Comparison of Power and Thrust Performance for a Fixed and Floating Offshore Wind Turbine

Wind Energy, Volume 29, Issue 6, June 2026.
ABSTRACT Floating offshore wind turbines have been identified as a critical technology for sustainable electricity generation. Wind resource assessment is used to determine optimal locations for floating wind farms. However, current methodologies do not account for performance differences between fixed and floating turbines due to wind‐ and wave ...

Wind Tunnel Assessment of Dynamic Induction Control Under Varying Inflow Wind Directions

Wind Energy, Volume 29, Issue 6, June 2026.
ABSTRACT Dynamic induction control (DIC), also known as pulse control, is a wake‐mixing strategy intended to improve wind farm efficiency by mitigating wake‐induced power losses. It typically employs harmonic collective blade pitching to excite wake instabilities, forming coherent pulsing structures that enhance turbulent mixing and accelerate wake ...

Simulation and Optimization of an Airfoil with Leading Edge Slat

Journal of Physics: Conference Series, 2016
A gradient-based optimization is used in order to improve the shape of a leading edge slat upstream of a DU 91-W2-250 airfoil. The simulations are performed by solving the Reynolds-Averaged Navier-Stokes equations (RANS) using the open source CFD code OpenFOAM.

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

Wind 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
