The paper describes the DAN-AERO MW experiments carried out within a collaborative, three years research project between Riso DTU and industrial partners LM Glasfiber, Siemens Wind Power, Vestas Systems finally utility company DONG Energy. main objective of is to establish an experimental data base which can provide new insight into number fundamental aerodynamic aeroacoustic issues, important for design operation size turbines. most issue difference airfoil characteristics measured under...
In this paper, measurements of the stall a NACA [Formula: see text] airfoil section are presented and compared to simulation with hybrid Reynolds-averaged Navier–Stokes (RANS)/large-eddy (LES) model goal gaining deeper insight into flow physics cell turbulent wake in such conditions. Detailed evolution velocity deficit turbulence within along surface pressure visualization provided comprehensive database for code validation studies.

Using flight measurements conducted between altitudes of 700 and 3000 m, this work characterizes atmospheric turbulence investigates the effects an increase in level on laminar–turbulent transition taking place pressure side a laminar airfoil. Flight conditions ranging from calm to moderately turbulent natural driven by Tollmien–Schlichting waves are considered. The inflow first characterized reported using single two-point statistics. Moreover, it is shown how characteristic parameters can...
Within the Luftfahrtforschungsprogramm (LuFo), measurements on a laminar flow airfoil in flight as well wind tunnel are combined with direct numerical simulations (DNS) to provide base for future improvements of transition prediction under unsteady inflow conditions. Two regions turbulent length scales particular interest investigating effect boundary layer straight wings: large leading pressure distributions and small corresponding streamwise wave lengths Tollmien-Schlichting (TS) waves...
Abstract Wind tunnel investigations of how Natural Laminar Flow (NLF) airfoils respond to atmospheric turbulence require the generation turbulence, whose relevant characteristics resemble those in atmosphere. The lower, convective part boundary layer is characterized by low medium levels turbulence. current study focuses on small scales this Detailed hot-wire measurements have been performed characterize properties generated grids mounted settling chamber Tunnel (LWT). In test section, very...
