CFD simulations reveal urban wind flow and pollution patterns
As part of the LIFE-NEEVE initiative, RDT is contributing to the understanding of wind flow and pollutant dispersion in complex urban environments.
Using the ENGYS Helyx CFD solver, we simulated the air flow across a dense urban district to identify ventilation corridors, recirculation zones, and areas prone to pollutant accumulation.
The results shown illustrate how building geometry modifies near-ground wind speeds and local flow patterns—key information for understanding how the pollutants move through the urban canopy.
These simulations support the project’s efforts to link real-world air-quality measurements with high-fidelity numerical modelling. Insights from this work will help inform urban planning strategies and guide the placement of sensors for more accurate exposure assessment.
