Currently, the wind turbine size is increasing dramatically, and the blades are experiencing large deformations. Accordingly, the aerodynamic force distributions over the blades are changed, and hence aeroelastic analysis has become of great importan

Meanwhile, a high fraction of vehicles, driven by diesel engines, is equipped with very efficient particle filters in Europe. The filters have been enforced by the particle number limit for type approval testing. If the filter works properly, the emi

The aeroelastic response of the generic DTU 10 MW horizontal-axis wind turbine blades is investigated employing a time-accurate CFD–CSD loose coupling approach. An FSI coupling approach is implemented and used to conduct the aeroelastic simulations

The present work introduces a method for the design of a boundary-layer suction system for turbulent trailing-edge noise reduction of wind turbines. Since the latter hitherto has been primarily assessed in a two-dimensional framework, the paper is me

International audience; Since the investigation of van Ingen et al., attempts were undertaken to search for laminar parts within the boundary layer of wind turbines operating in the lower atmosphere with much higher turbulence levels than seen in win

The unsteady aerodynamics of a scaled model floating horizontal-axis offshore wind turbine is investigated numerically. Different aerodynamic models are used to analyze the complex unsteady flow, namely models based on unsteady Reynold-Averaged Navie

A semi-empirical model to determine the wall pressure frequency spectrum beneath a two-dimensional, pressure gradient turbulent boundary-layer is presented. The model is derived based on the experimental wall pressure data of various research groups.

In the present paper an approach to derive anisotropic turbulence properties from standard Reynolds-averaged Navier-Stokes simulations is proposed. The theory includes models for anisotropic velocity spectra and scaling functions that can be used to
