Particle concentration measurement by various methods
Kuruc, Jan ; Kalivodová, Markéta (referee) ; Sitek, Tomáš (advisor)
In addition to the gaseous components, the Earth's atmosphere contains solid and liquid particles from various sources. These particles are monitored and examined mainly due to their environmental and health impacts and many methods are used for their monitoring and measurement. The aim of the research part of this thesis is to bring the topic of aerosol particles, namely their division, the methods of formation closer, to indicate the impact of these particles on the environment and human health, and to further describe the measuring instruments used to measure the concentration of fine particles. The practical part of this work is the measurement of particle concentration using the impactor, the monitoring of particle concentrations and other data measured by the Brno-Arboretum measuring station, as well as the subsequent evaluation of the measured and monitored data. The primary output from the almost 18-day impactor measurement is considered to be the total concentration of all captured particles of 11.56 g/Nm. The size distribution of the captured particles is plotted in the graph, as well as the quantities monitored from the station. The data obtained is compared at the end and the links linking these data are given.

Heat transfer from the surface of the human body - validation of a CFD thermal manikin model
Kuruc, Jan ; Pokorný, Jan (referee) ; Fišer, Jan (advisor)
This master thesis is focused on CFD simulation of heat transfer from a thermal manikin in a calibration environment and its subsequent validation based on the experiments already performed in the master thesis of Ing. Fojtlín and Ing. Hrubanová. The main objective of the work is to find and test a suitable combination of physical models and set boundary conditions in the simulation model so that the actual heat transfer and airflow processes from the validation experiments are faithfully simulated. In the course of the work, 7 cases were simulated based on individual measurements made during the experiments. The calculated heat transfer coefficients of the thermal mannequin segments for each simulated case can be considered as the main results of the simulation. For the experiment of Ing. Fojtlín, these are the heat transfer coefficients by radiation and convection. For the experiment of Ing. Hrubanová, the total heat transfer coefficients for a manikin with five selected clothing assemblies were determined. Validation was performed by comparing the simulated and experimentally determined values of heat transfer coefficients. Based on the comparison, the developed simulation model could be declared validated.
