RISNonlinear Lifting Line Theory Applied to Vertical Axis Wind Turbines: Development of a Practical Design Tool
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recently, a new interest in vertical axis wind turbine (VAWT) technology is fueled by research on floating support structures for large-scale offshore wind energy application. For the application on floating structures at ...
Development of a Fluidic Actuator for Adaptive Flow Control on a Thick Wind Turbine Airfoil
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Wind turbines are exposed to unsteady incident flow conditions such as gusts or tower interference. These cause a change in the blades' local angle of attack, which often leads to flow separation at the inner rotor sections. ...
Implementation, Optimization, and Validation of a Nonlinear Lifting Line Free Vortex Wake Module Within the Wind Turbine Simulation Code qblade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The development of the next generation of large multimegawatt wind turbines presents exceptional challenges to the applied aerodynamic design tools. Because their operation is often outside the validated range of current ...
Effects of Airfoil's Polar Data in the Stall Region on the Estimation of Darrieus Wind Turbine Performance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Interest in vertical-axis wind turbines (VAWTs) is experiencing a renaissance after most major research projects came to a standstill in the mid 1990s, in favor of conventional horizontal-axis turbines (HAWTs). Nowadays, ...
Three-Dimensional Aerodynamic Analysis of a Darrieus Wind Turbine Blade Using Computational Fluid Dynamics and Lifting Line Theory
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Due to the rapid progress in high-performance computing and the availability of increasingly large computational resources, Navier–Stokes (NS) computational fluid dynamics (CFD) now offers a cost-effective, versatile, and ...
Static and Dynamic Analysis of a NACA 0021 Airfoil Section at Low Reynolds Numbers Based on Experiments and Computational Fluid Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The wind industry needs airfoil data for ranges of angle of attack (AoA) much wider than those of aviation applications, since large portions of the blades may operate in stalled conditions for a significant part of their ...
