| 内容記述 | We consider the galloping oscillations of prisms with square and 2/3 rectangular section. Rigid prisms are flexibly mounted in wind tunnel. Energy harvest is performed by a series of magnets mounted on the oscillating prism so that they pass close to the face of a coil-core system externally fixed. The produced power is dissipated through a decade box allowing adjustment of the load resistance. A simple mechanical analysis leads to define several efficiencies for such a galloping setup: the global efficiency is the ratio between electric power and wind power. It is the product of two efficiencies: the ratio of the galloping power referred to wind power, and the one being the electrical power referred to the galloping power. Galloping power is the maximum power that can be extracted from the oscillations of the prism which are governed by the aerodynamic damping and structural damping. It is always found very small compared to wind power. Experimental results notably show that there exists an optimal load resistance for global efficiency while another optimal value is found for the electrical production referred to the galloping power. | |||||||||||
