Original abstract
In this paper authors compare two different approaches of 10 m particles (PM10) dispersion modelling in urban areas. The study is focused on comparison of the Eulerian-Lageangian approach accurately describing particle aerodynamics and the passive scalar approach representing simplified alternative for description of dispersion processes. CFD code StarCD has been used for this study as appropriate tool capable of correct velocity field prediction and inclusion of both approaches. A street canyon with intensive traffic located in the central part of the city of Brno is used as a convenient study area. The numerical predictions obtained by both tested approaches are compared with an in situ measurement carried out in the studied street canyon. To simulate traffic, an original model developed previously by the authors is used that takes into account traffic density, speed of cars and number of traffic lanes.

V článku autoři popisují testování dvou odlišných matematických modelů užitých pro řešení disperze prachových částic podél dopravních cest v městském prostředí. Testován je konkrétně Eulerův a Lagrangeovský přístup popisu pohybu částic. Jako modleová oblast byla použita část městské zástavby ze středu města Brna.
