Performance Assessment of an Aeolian Roof for the Exploitation of Wind Power in Urban Areas

In this work, an innovative system for depletion of wind power in urban areas is presented. The energy conversion system is installed in the place of the roof of the civil building, carrying out the same covering functions, but at the same time it conveys the air flow towards a vertical axis centripetal turbine. The studied system makes it possible to avoid some typical drawbacks of the eolic generation, such as the encumbrance of the blades, noise, cut-in and cut-off velocities of the wind, presence of turbulence. Due to these problems, the wind energy usually is not considered as a suitable energy source for the urban areas. In this work, a study has been performed in order to assess the potentialities of the proposed system for fulfilment of energy demands in urban areas. By means of a finite element analysis, the sensitivity with respect to the design parameters will be evaluated.
