Microclimate and urban planning

Wind flow around the blocks and computed vs measured normalized wind speeds


Validations and applications of a CFD tool dedicated to wind assessment in urban areas 


UrbaWind is a CFD code developed by Meteodyn especially dedicated to urban wind applications with an automatic meshing and boundary conditions set-up.

The paper shows validations by comparisons with experimental data proposed by the Architectural Institute of Japan (Tominaga et al., 2008).

The first selected case is a wind-tunnel experiment of wind past a group of blocks, and the second one is a field experiment inside a quarter Niigata (Japan). 

Three examples of application in the outdoor comfort assessment are presented: A pool deck of Mosaic Houston (Texas), Chambéry Hospital (France), Saint-Brieuc district (France).
