Abstract
This chapter provides a synopsis of an emerging consensus on methodologies for conducting assessments of wind flow resources in the urban environment. Such evaluations of the urban turbulent flow are becoming more common, as the value of such information is realized for assessing building planning, ventilation and exhaust design, urban wind energy harvesting, placement of solar modules, and comfort of pedestrians around these structures. This chapter places emphasis on wind resource assessment for the use of wind energy harvesting, and it notes the growing body of research pointing to accepted methods for combining experimental data collection with CFD modelling to optimize the placement of small wind turbines (SWT). The experimental research points to a changing view on the accepted 10 min averaging times used for calculating turbulence statistics. Specifically, recent results revealed significant effects of shorter averaging time on the turbulence intensity, which may be relevant for SWT. CFD models tend to use RANS closures with modified and nonlinear models. These aim to accurately predict the mean effect of unsteady recirculation around rooftops, where wind harvesting devices are likely to be installed. This review documents the multitude of approaches, showing the current trends toward standardized method of wind resource assessment.
