Etude numérique et expérimentale de l'écoulement autour d'un rotor éolien [PDF]
An improved model of an actuator surface is proposed, representing the flow around a wind turbine. This model was developed in conjunction with a Navier-Stokes solver using a blade element method for the calculation of power and wake development.

Testing of calibration models in order to certify the overall reliability of the trisonic blowdown wind tunnel of VTI [PDF]
It is strongly recommended that wind tunnel calibrations become a regular part of the operational cycle for any wind tunnel. They facilitate tunnel-totunnel data comparisons. Standard calibration model, representing a generic winged missile configuration,

Contemporary frame of measurement and assessment of wind-tunnel flow quality in a low-speed facility [PDF]
The requirements for the accuracy of measurements in a wind tunnel test become more and more severe while the complexity of the test increases. In an environment of reduced time available for wind tunnel test and increasing test costs, it is important ...

The Wind-tunnel Test and Unsteady CFD of an Ornithopter Formation [PDF]
According to Lissaman and Shollenberger’s article published in Science in 1970, birds fly in formation to reduce the overall energy expenditure for flight. Thus, this work adopted the same principle of flight formation to ornithopters to save energy. Two
