3 ResultsThis project presents a two-dimensional Computational Fluid Dynamics (CFD) analysis of pollutant dispersion in an idealized urban street canyon. The study investigates the influence of street canyon aspect ratio (H/W = 0.5, 1.0, and 2.0) on airflow recirculation and pollutant concentration under steady, incompressible flow conditions. Carbon monoxide (CO) is considered as a passive tracer to represent traffic-related emissions. Simulations are performed using the standard k–ε turbulence model with perpendicular wind conditions. The objective is to evaluate the impact of urban geometry on street ventilation and pollutant removal, providing a simple benchmark study for undergraduate research in urban environmental fluid mechanics.
