Context and objectives

The City of Grenoble wants to assess the local air quality impact of a road modification on the surrouding areas. Sensitive targets like schools can be found in the domain of interest and the pollutant concentration needs to be estimated accurately.

Our success

By integrating the buildings and obstacles all around the road sectors, Fluidyn has carried out 3D-CFD simulations of the flow patterns and pollutant dispersion to assess the people exposure. The performance of a wall along the road on the local air quality improvement has also been modeled. Simulations provided as well design elements for the road closest buildings ventilation.
