Determining tower top acceleration of a wind turbine

It is important to be able to obtain accurate measurements of the acceleration of a wind turbine, in particular of the top of the wind turbine tower or of the wind turbine nacelle. This...

Compact wind acceleration turbine

OverviewPerformanceHistoryEconomicsOptiwindOgin (formerly FloDesign Wind Turbine)

The science of wind acceleration around a structure, as well as the vortex shedding benefits of a shroud/diffuser, are well understood and tested. From Bernoulli forward, science has substantially vetted these concepts and there is general academic consensus as to their veracity and their potential impact on wind power production. DAWT''s however have the classic boundary layer separation problem experienced by airfoils at a "stall" angle of attack. This significantly reduces t

Flow acceleration statistics: a new paradigm for wind-driven loads

Further, in contrast to wind speed statistics, acceleration literally represents the forcing of the flow on turbine structures; as described later below, it does not require
