Abstract

Renewable energy exploitation in the urbanized areas has been receiving an increased attention over recent years because the proximity to electricity users makes it possible to obtain better global efficiency and to save territory. In this work a new wind energy system that uses the roof of the building in combination with a centripetal turbine is presented. This could be considered as an amplifier of the wind speed that should allow the wind turbine to work under both lower and higher velocities than the conventional aerogenerators and therefore to increase its delivered power output. Considering the local wind climate of the area of interest, in this work, firstly, a Computational Fluid Dynamics (CFD) model is used to simulate the flow into the eolic system. Then, a laboratory-scale prototype has been made in order to test the potentialities of the proposed system for fulfillment of energy demands.
