| Abstract [eng] |
Air pollution by solid particulates in urban areas is one of the most pressing environmental problems. Increased number of particles is associated with increased incidence of cardiovascular, respiratory and other diseases as well as negative influence on mechanisms and buildings. As a result, this thesis is addressed to analyse traffic-related air flows, speed of particle dispersion as well as aimed at design of construction blocks with integrated cyclones. The designed blocks with integrated cyclons could be used for particulate matter collection and passive cleaning of ambient air. The analysed scientific publications are focused on determination of main properties of particulate matter, formation and releases into the ambient air sources and possible impacts on human health. Also, detailed examination of dynamics of particles in the environment of road transport was perfomed. Furthermore, it was considered possible application of cyclon blocks in to the construction of acoustical walls. In order to achieve the aims of the thesis, specialised computer software Solid Works was applied. The following parameters were analysed: air flow propagation path, behavior and speeds approaching the wall. Moreover theoretical calculations were carried out to identify particle speed limit, efficiency and pressure loss of cyclones. Based on the obtained characteristics custom configuration of the cyclone was selected. Cyclon block was materialised by using 3D printing technology. Finally, possible application areas of cyclon blocks were discussed. |
