114808 - "Wind Power Distributed Generation Analysis in Urban Areas, a Case study." 

Wind velocity profile around high-rise buildings in urban areas are influenced by their shapes and arrays. The objective of this investigation is to assess the feasibility of a distributed power generation from wind turbines mounted in these buildings.
This investigation intends to give a better understanding of the influence that buildings have on the wind’s velocity profile in different atmospheric conditions, as well as the influence their structural shape and their array configuration is on the wind velocity profile. Subsequently it will be possible to justify the optimal location for the installation of the wind turbine, information which is particularly useful for both, architects and engineers who work on the design and planning of new buildings with the potential of exploiting wind’s power. Also, it is within the motivation of this study to encourage further energy exploitation, which is widely regarded as a renewable energy source. This type of energy source is unfortunately not yet fully developed in Paraguay.
Wind’s aerodynamics and its flow through buildings are analyzed in different conditions based on meteorological data for the area of analysis. A set of four buildings located in a specific location in the city of Asuncion is analyzed. Actual dimensions of these towers were utilized. Historical wind velocity data were utilized as boundary conditions. A particular direction was focused in this study i. e., north-east direction. This has been observed to be more frequent in the site. This data will prove to be useful to obtain further information which will determine the convenience of the use of small sized wind turbines.
The election for the site of study was motivated since it showed no nearby taller buildings that could further influence the flow of the wind, as well as no significant slopes in the topology of the neighboring terrain. In addition, these towers have been built in an asymmetric manner, this would be ideal for a better understanding of flow pattern correlation.
The computational tool used for this air flow simulation was SolidWORKS Flow Simulation, a commercial software from the company Dassault Systemes. The three-dimensional model was generated using the same software. Results from CFD (Computational Fluid Dynamics) showed a specific high-speed spot located nearby one of the four buildings analyzed in this case study. However, this location was not as convenient as the second but lower high-speed spot. This last one was observed to be between two buildings. The building developers recommended the second option as this was a more feasible configuration for a wind turbine structure to me installed.
