WINDENERGY HARVESTOF HIGH-RISEVOID BUILDINGSAT VARIED URBAN PATTERNS
Abstract
Abstract - This paper explores the effect of urban pattern on the wind energy potential around a generic 2×2 high-rise void building array in an urban environment. To evaluate obtainable wind resources, the computational fluid dynamics (CFD) software ANSYS Fluent® v19.2 is applied to solve the distributions of wind velocity, power density (PD) and turbulence intensity (Ti) atthe varied widths between upstream and downstream buildings. The calculated dimensionless velocity (u/uref) and turbulence intensity (Ti) are compared with the measured data from the wind-tunnel experiments to verify the numerical model. The simulated results reveal that the design of upstream void buildings induces more uniformly distributed airflows into lateral canyons to enhance air aeration development. Increasing street width (from 9 m to 21 m) tends to produce better outcomes of elevated wind speeds over the void channel, extending into lateral streets. The obtained results can be useful to provide the design reference for urban wind energy utilization.
