Original abstract

This paper presents an assessment of an influence of turbulence intensity in a vicinity of a linear pollution source on the consequent process of air pollutant dispersion in an urban environment. 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 generation of turbulence above the traffic path. The influence of generation of the kinetic energy of turbulence by a linear source on the concentration of PM10 at various points of a studied area is obtained by using the mathematical modelling method CFD. Assessment of obtained results defines a relation between the PM10 concentration at a ground-level air layer and the kinetic energy generated by a linear source.
