Design studies on building-integrated wind energy using CFD simulations.

The present research uses a computational fluid dynamics (CFD) approach to develop a three-dimensional digital model for determining the potential power for delivering stable electricity in maximizing the use of wind energy in a high-density urban area. In consideration of the scenario of placing micro-wind turbines to the planned site in the Integrated Technology Complex building (ITCB) of National Taipei University of Technology, Taipei, Taiwan, the outdoor wind environments were resolved to identify the most appropriate locations of installing micro-wind turbines. In the analysis, we considered the incompressible isothermal turbulent airflow to examine the interaction of the wind with the building complex for resolving the velocity magnitude and turbulence intensity contours. The CFD results indicated the roof as the most suitable site for installation of wind turbines, as compared to the mounting sites on the corridors and other low floors.
