Designing Emission from the Point of View of Geometric Parameters of the Emitter

The paper presents the calculation results of the concentration of particles suspended in the air, taking into account various geometric parameters of the emitter and especially its height and diameter on the given examples. The situations where the emitted pollution comes from low emitters characteristic for single-family households, and then also from emitters of industrial type as well as high chimney stacks characteristic for thermal power plants were considered. For the cases mentioned above, modelling of the geometric parameters of an open point source was performed. The visualisation of results, presented in isoline maps of PM10 dust concentrations, has enabled to conduct an analysis of differences in immission and dispersion of the particles suspended in the air within the diameter ten times larger than the height of the point source/emitter.
