de Vries, O. (author)The commonly used blade-element theory predicts a zero yawing moment in the time-average sense. Small-scale wind-tunnel experiments at the Eindhoven University of Technology revealed stable yawing moments at almost all operating conditions with the rotor in an upwind position with respect to the tower. The present comment shows, that this...report 1984

de Vries, O. (author)The deformation of the vortex sheet "behind a 30 sweptback wing (span 1.5 m, chord 0.3 m) has heen measured in the LST 3x2. Three types of measurements have been applied: - a total head survey (viscous wake) - yaw measurements (sidewash variation across vortex sheet) - vortex indicator measurements (vortex wake). Only a part (60%) of the total...report 1973

de Vries, C. (author)Late Scandian (400 – 425 Ma) exhumation in the Scandinavian Caledonides involved extensive displacement along several shear zones. The Western Gneiss Region (WGR) hosts one of these detachments also called the Nordfjord-Sogn detachment shear zone (NSDZ). It is still unclear to what extent this shear zone was involved in the exhumation of Baltica...report 2008

de Vries, O.H.M. (author)In dit rapport wordt de in augustus 1986 gehouden NPOC-SPOT enquête besproken. Deze enquête is gehouden in opdracht van de Beleidsconnnissie Remote Sensing (BCRS), naar aanleiding van de start van het Nationaal Remote Sensing Programma (NRSP). De enquête was bedoeld om inzicht te krijgen in de markt mogelijkheden voor EARTHNET en SPOT satelliet...report 1986

Prins, A. (author), de Vries, M. (author)Often the need is felt to schematize a river regime by one single discharge, the Dominant Discharge, and to use this discharge for prediction of changes in a riverstretch as a consequence of riverworks. This article discusses some methods, as given in literature, to determine the Dominant Discharge and gives a way to compute this discharge by...report 1971

Labrujere, T.E. (author), Schipholt, G.J. (author), de Vries, O. (author)The applicability of potential flow calculations for developing high-lift devices, is evaluated by comparing calculated pressure distributions over wing sections with trailing and leading edge high-lift devices, and experimental results, obtained during routine wind tunnel tests.report 1972

de Vries, O. (author)A two-bladed horizontal-axis wind turbine, with a diameter of 0.75 m and a solidity ratio of 0.0674, has been tested in the LST 3 x 2 of NLR. Most of the tests have been carried out at an almost constant Reynolds number of about 3.5 X 10/5. Comparison with a simple performance prediction method showed an acceptable agreement in qualitative...report 1979
