RISExtension of a Helicoidal Vortex Model to Account for Blade Flexibility and Tower Interference
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The unsteady vortex method has been extended to account for blade flexibility and tower interference. These are two potential sources of unsteadiness of the flow past a wind turbine blade. The ...
Optimization of Wind Turbines Using Helicoidal Vortex Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The problem of the design of a wind turbine for maximum output is addressed from an aerodynamical point of view. It is shown that the optimum inviscid design, based on the Goldstein model, ...
A Parallelized Coupled Navier-Stokes/Vortex-Panel Solver
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A Navier-Stokes solver, CFX V5.6, is coupled with an in-house developed Vortex-Panel method for the numerical analysis of wind turbines. The Navier-Stokes zone is confined to the near-field ...
Characterization of Three-Dimensional Effects for the Rotating and Parked NREL Phase VI Wind Turbine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper addresses three-dimensional effects which are pertinent to wind turbine aerodynamics. Two computational models were applied to the National Renewable Energy Laboratory Phase VI Rotor ...
