Influence of vehicle-induced turbulence on pollutant dispersion in street canyon and adjacent urban area

Popis výsledku v původním jazyce

This paper presents an assessment of an influence of turbulence intensity in the close vicinity of a linear source of pollution on the consequent process of air pollutant dispersion in an urban environment. Turbulent flow structure in a vicinity of vehicles in motion significantly influences the dispersion of air pollutant generated by road traffic into the environment of a traffic path. Higher turbulence intensity results in a greater stir of air. The detailed investigation of cross section vortex in the street canyon is done by the computational parametrical study. Pollutant dispersion is monitored at a specific segment of an urban area crossed by a straight traffic path. The traffic path represents a studied linear source of pollution. Vehicles' motion along the traffic path has been considered as an input parameter for the consequent quantification of the kinetic energy of turbulence generation above the traffic path. The influence of generated kinetic energy of turbulence by linear road on the concentration of PM10 at receptor points located in the studied area is obtained by using the mathematical modelling method CFD. Assessment of the results gained defines a relation between the PM10 concentration at a ground-layer of air and the kinetic energy generated by a linear source.
