Resumo

The article is about the analysis of the various cross-sectional shapes of energy-efficient high-rise buildings towers equipped with integrated wind turbines influence on their aerodynamic parameters. Three variants of the tower base plan shape are proposed: rectangular, triangular and triangular with rounded corners. Modeling of the models aerodynamic flow was simulated in the ANSYS software and computing complex using the ANSYS CFX computational fluid dynamics module for two wind attack directions of 0о and 45о to the main facade. A comparative analysis of the high-rise complex towers models was carried out to identify the optimal configuration ensuring the stable air flow formation in the wind turbines vicinity and maximizes energy production. It was found that the triangular cross-section with rounded corners of the tower provides the best combination of aerodynamic characteristics, power generation efficiency and minimizes the vortex shedding likelihood.
