Abstract: A two-dimensional analysis of the performance and flowfield of the Giromill is presented. The Giromill is a vertical-axis wind turbine with straight blades that are articulated to produce maximum ...

Abstract: The FAST Code which is capable of determining structural loads of a flexible, teetering, horizontal axis wind turbine is described and comparisons of calculated loads with test data are given ...

Abstract: A theory for vertical axis wind turbines has been developed using a fixed wake approach. The theory combines some of the best features of vortex and streamtube approaches. This approach accounts ...

Abstract: A free-vortex analysis of a Darrieus rotor blade in nonsteady motion has been developed. The method uses the circle theorem to map a moving airfoil into the circle plane. The wake is modeled ...
