The NASA-LeRC wind turbine sound prediction code [PDF]

Since regular operation of the DOE/NASA MOD-1 wind turbine began in October 1979 about 10 nearby households have complained of noise from the machine. Development of the NASA-LeRC with turbine sound prediction code began in May 1980 as part of an effort ...

Validation of wind turbine wake models

, 2018
Wind turbine wakes have a strong impact on wind farms given that they affect the power output and the level of turbulence that determines the turbines lifetime. Thus, wake modelling is of critical importance to the wind energy industry, having a central role in the optimization of wind farm layouts.

Numerical computations of wind turbine wakes

, 2005
Numerical simulations using CFD methods are performed for wind turbine applications. The aim of the project is to get a better understanding of the wake behaviour, which is needed since today’s industrial design codes for wind power applications are based on the BEM (Blade Element Momentum) method.

Wind turbine wakes : controland vortex shedding

, 2004
Wind tunnel studies of the wake behind a model wind turbine have been made in order to get a better understanding of wake development as well as the possibility to predict the power output from downstream turbines working in the wake of an upstream one. Both two-component hot-wire anemometry as well as particle image velocimetry (PIV) have been used to
