Investigation of the Dynamic Characteristics of PM<sub>2.5</sub> Dispersion During the Acceleration of Motor Vehicles in Urban Streets Based on Computational Fluid Dynamics and Dynamic Mode Decomposition

Investigation of the Dynamic Characteristics of PM<sub>2.5</sub> Dispersion During the Acceleration of Motor Vehicles in Urban Streets Based on Computational Fluid Dynamics and Dynamic Mode Decomposition

Vehicle acceleration typically occurs at traffic lights, intersections, or congested sections within urban streets, where high densities of pedestrians and vehicles pose a direct threat to respiratory health due to PM<sub>2.5</sub> dispersion. Computational Fluid Dynamics (CFD) simulatio...
