The development of new energy vehicles and road dust removal technologies presents opportunities for constructing urban ventilation systems based on patterns. However, the impact system layouts pedestrian-level wind environments remains insufficiently understood. This study utilizes general-purpose CFD software Phoenics to analyze effects orientation, width, density, intersection configurations block ventilation. standard k-ε model three-dimensional steady-state RANS equations are employed calculate mean air age as an indicator efficiency. Grid convergence analysis validation against previous tunnel measurements were conducted. Results show that influence overall efficiency by affecting airflow volume, direction, velocity. Optimal occurs when orientation aligns with prevailing at 0° or exceeds 70°. Recommended widths trunk, secondary, local roads 46 m, 30 18 respectively. Lower densities enhance ventilation, while higher trunk secondary beneficial. Intersection distribution, windward segments aiding lateral side roads. Finally, design strategies proposed, offering potential leveraging networks construct efficient systems.
