Main Results from Investigation of Aerodynamics, Structural Dynamics and Fatigue on Danwin kW By F. Rasmussen, S. Markkilde Petersen and A. Kretz .   In addition, the investigation determined that the wind direction of ° yielded most favorable results with a maximum power production capacity of kW indicating a high capacity factor of 13 %. Chong et al. conducted a study on the design of a wind turbine generator for the purpose of energy consumption in buildings.

In this study, the fatigue life of a medium scale ( kW) horizontal axis wind turbine system (HAWIS), which has been developed by the present study, was estimated by using the well-known S–N. Flapping wing flight as seen in hummingbirds and insects poses an interesting unsteady aerodynamic problem: coupling of wing kinematics, structural dynamics and aerodynamics.

Darris et al. analyzed the importance of load phase angle variations on fatigue damage using fatigue aerodynamics structures and turbulences (FAST) dynamics model and it had been observed that variable phase angle fatigue testing can influence the distribution of damage around the blade profile. Fingersh conducted Unsteady Aerodynamics Cited by: The objective of this paper is to numerically investigate the effects of the atmospheric boundary layer on the aerodynamic performance and loads of a novel dual-rotor wind turbine (DRWT). Large eddy simulations are carried out with the turbines operating in the atmospheric boundary layer (ABL) and in a uniform inflow. Two stability conditions corresponding to neutral and slightly stable Cited by: E. Bilge, in Vehicle Thermal Management Systems Conference and Exhibition (VTMS10), Aerodynamic analysis. The main reason of the aerodynamic analysis is to determine drag coefficient of the vehicle which affects fuel consumption, predict low and high pressure areas, separation points and down force which affects vehicle dynamics. All these parameters are also investigated deeply in. W.A. Timmer, C. Bak, in Advances in Wind Turbine Blade Design and Materials, Investigation of airfoil contour. When it is decided to predict the aerodynamic performance of a 2-D airfoil contour the coordinates for this airfoil should be provided in terms of x and y coordinates. Often the coordinates are normalized with the chord length, so that the resulting coordinates are x/c and y/c 1.
