Wind Energy Potential Research in a Low Building within an Urban Environment
The use of wind energy for distributed generation in urban environments, where the intensity of turbulence begins to be a decisive factor, is currently one of the main challenges within renewable energies.
Wind tunnel tests have evaluated shaped buildings that can capture wind within the urban atmospheric boundary layer by directing them to wind turbines located in the building so that they produce electricity. In particular, this work evaluates a low building within the city of Neuquén, in Patagonia, Argentina.
The methodology consisted in constructing a 1:200 scale model, performing wind tunnel tests to characterize the flow pattern on the roof of the tunnel. Wind measurements were also performed for two years with an automatic weather station on the roof of the building. The possible power generation was modeled with two prototypes of small wind turbines: one of horizontal axis and one of vertical axis, both developed in the zone. The annual energy savings that could be achieved would be of the order of 20%.
