A model for the effect of pressure gradient on the induction and power of wind turbines

Fernando Porté Agel, Arslan Salim Dar, Tristan Revaz

Recent studies have shown that streamwise variations in base flow velocity and the resulting pressure gradients can affect the induction and power of wind turbines. However, current research lacks analytical models that explicitly predict the effect of pre ...

Effect of hills on wind turbine flow and power efficiency: A large-eddy simulation study

Fernando Porté Agel, Tristan Revaz

This study investigates the influence of topography on wind turbine flow and power efficiency. Specifically, a standalone wind turbine is positioned at the top of idealized two-dimensional hills, and the effects of hill geometry and turbine position are sy ...

Numerical Framework for Aerodynamic Characterization of Wind Turbine Airfoils: Application to Miniature Wind Turbine WiRE-01

Fernando Porté Agel, Tristan Revaz, Mou Lin

A numerical framework for the aerodynamic characterization of wind turbine airfoils is developed and applied to the miniature wind turbine WiRE-01. The framework is based on a coupling between wall-resolved large eddy simulation (LES) and application of th ...
