Analysis of the high Reynolds number 2D tests on a wind turbine airfoil performed at two different wind tunnels

2D wind tunnel tests at high Reynolds numbers have been done within the EU FP7 AVATAR project (AdVanced Aerodynamic Tools of lArge Rotors) on theDU00-W-212 airfoil and at two different test facilities: the DNW High Pressure WindTunnel in Gottingen (HDG) and the LM Wind Power in-house wind tunnel. Two conditions of Reynolds numbers have been...

Analysis of high Reynolds numbers effects on a wind turbine airfoil using 2D tunnel test data

The aerodynamic behaviour of a wind turbine airfoil has been measured in a dedicated 2D wind tunnel test at the DNW High Pressure Wind Tunnel in Gottingen (HDG), Germany. The tests have been performed on the DU00W212 airfoil at different Reynolds numbers: 3, 6, 9, 12 and 15 million, and at low Mach numbers (below 0.1). Both clean and tripped...

Bepaling van de Healingscapaciteit van een asfaltmengsel

In de shift-factor van 4 die wordt gebruikt in de Ontwerp Specificaties van Rijkswaterstaat zit onder andere het effect van de zelf-healing capaciteit van asfalt ten gevolge van rustperioden in de belasting die in de praktijk wel en in laboratorium proeven voor vermoeiing niet aanwezig zijn. De grootte van deze factor is bepaald aan de hand van...

Testing and modeling of diffusion bonded prototype optical windows under ITER conditions

Glass-metal joints are a part of ITER optical diagnostics windows. These joints must be leak tight for the safety (presence of tritium in ITER) and to preserve the vacuum. They must also withstand the ITER environment: temperatures up to 220°C and fast neutron fluxes of ∼3·10 9 n/cm 2·s. At the moment, little information is available about glass...

17α-Ethyl-5β-estrane-3α,17β-diol, a biological marker for the abuse of norethandrolone and ethylestrenol in slaughter cattle

The metabolism of the illegal growth promoter ethylestrenol (EES) was evaluated in bovine liver cells and subcellular fractions of bovine liver preparations. Incubations with bovine microsomal preparations revealed that EES is extensively biotransformed into norethandrolone (NE), another illegal growth promoter. Furthermore, incubations of...
