Contribution à la transition dans la couche limite

Hinze, J.O. (author), Leijdens, H. (author), Van den Brug, J.B. (author), Kleiweg, D. (author)

A l'aide de la méthode du ruban vibrant de Schubauer et Klebanoff. on a étudié expérimentalement l'évolution tridimensionnelle d'une perturbation sinusoïdale locale introduite dans une couche limite laminaire. Les distributions de la vitesse moyenne et de l'intensité de la composante axiale de la turbulence, de même que le spectre d'énergie de...

Empowering AMA

Yi, W. (author), Ye, H. (author), Van Merle, O. (author), Asarpota, K. (author)

The dependence of the economy on fossil fuels and the lack of stringent policies to extensively implement renewable energy is an issue to be tackled at national level in the Netherlands. Reducing emissions, while making the shift to renewable energy and changing the existing energy systems towards a sustainable model has been discussed widely....

Reynolds number effects on pressure and normal force distributions along conically pointed circular cylinder at free-stream mach number of 2.3

Boersen, S.J. (author)

Pressure measurements have been carried out on 5 stations along a 7.5- caliber conically pointed circular cylinder at a Mach number of 2.3 and Reynolds numbers of 1.2; 4.8 and 11.1 x 106. Pressure distributions have been integrated to produce local normal force coefficients. Some pitot pressure surveys have been performed in the external flow...

Boudary layer measurements on a two-dimensional wing with flap

van den Berg, B. (author)

An experiment is described on a wing flap configuration, which was so designed that nowhere flow separations occur, apart from a small laminar separation bubble on the wing nose. The measurements comprise surface-pressure measurements, boundary layer and wake traverses, and surface-flow visualizations. Three angles of attack have been applied...

Boundary-layer effects in unsteady pressure measurements with tubes

den Boer, R.G. (author)

An experimental investigation revealed that the d5mamic response of a given pressure tube depends not only on the mean local pressure and the frequency, but also on the pressure amplitude and the boundary-layer at the tube entrance. By analyzing the flow at the entrance of the tube, the parameters are determined, which possibly play a role in...

Potential applications of laser anemometry for in-flight measurements

Jentink, H.W. (author)

This report concerns the application of laser anemometry for flight testing and other aircraft-related measurements. The laser anemometry technique and previous work in this field are reviewed and applications are described. A comparison of possibilities of laser anemometry with conventional techniques shows some unique advantages of laser...
