Abstract

The present work investigates the ventilation performance of a compact area in Rome, Italy, performing 3D steady-state Reynolds-averaged Navier–Stokes simulations for twelve wind directions. The urban ventilation is expressed in terms of the spatially averaged mean wind speed ratios at pedestrian level, γ_ped, and at 10 m height, γ₁₀. The urban morphology is quantified using morphological parameters (MPs). The relations between each MP and γ_ped and γ₁₀ are expressed through simple models obtained using linear regression analysis. The relations present strong correlations with R² up to 0.89. The provided linear models can be valuable tools for highlighting areas potentially vulnerable to poor air conditions without running simulations.
