Comparative Analysis of Shapes of the Energy-Efficient Buildings with the Integrated Turbine Wind Generators

Abstract

The paper analyzes a problem of the possible power generation using the wind generators installed within the urban areas, rather than at the isolated locations far from the populated areas. It considers feasibility of integrating wind generators into the urban environment on the example a high-rise buildings complex. The complex consists of two vertical buildings tapering in height and positioned in such a way that their surfaces act as structures for capturing and drawing wind flows into the power-generating units. The paper provides a numerical computer simulation of the aerodynamic flows acting on the towers with the three cross-sections from the least streamlined to a cross-section with the smoothed corners having the most gradual shapes. It analyzes the building shape influence on the velocity of a flow passing through the wind generator at the two characteristic angles of attack, and compares the efficiency of positioning the units at different heights between the two towers. The comparison is made using the velocity increase coefficient, as a more objective indicator that takes into account alteration in velocity as the flow approaches the building and enters the wind generator. The paper shows that using the smoother shapes for an object is most efficient, as they maintain comparative characteristics of the flows entering the power-generating units while providing the lowest aerodynamic resistance
