Numerical Tools Dedicated to Wind Engineering in Large Urban Area

Abstract

This paper presents a global methodology to compute wind flow in complex urban areas in order to assess wind pedestrian comfort, wind energy, wind safety or natural ventilation potential. The numerical tool presented here is composed of a CFD software suite covering both regional scale (20 km) and urban scale (1km), and able to model the wind in any complex terrains and in large urban environments. Examples are presented in the paper in order to show the advantages of the methodology for urban designers.

Atmospheric wind characterisation for power generation

“…Thus, an accurate representation of the boundary-layer wind profile of the inflow winds is necessary to produce accurate model results. Aside from wind energy, other fields also use CFD-based solvers for atmospheric transport problems such as in air quality management, pollution dispersion modelling, and urban air flow management [117,118].…”
