Biomass drying
Kroupa, Zdeněk ; Špiláček, Michal (referee) ; Baláš, Marek (advisor)
The bachelor thesis deals with drying of biomass and balance calculation of specified drying equipment. The task is to calculate the amount of flue gas needed to dry 170 kg of fermentation with a moisture content of 50% to 15%.

Dependence of flow properties of plastics on water content and technological parameters
Ohnút, Lukáš ; Šilhavý, Miroslav (referee) ; Kandus, Bohumil (advisor)
Bachelor thesis was focused on detection the effect of moisture on the injection process. Two commonly used materials polyamide (PA66) and polybutylene terephthalate (PBT) were selected in the first step. The polymers were characterized to moisture analysis to determine the moisture content depending on time and temperature of drying. The experiment was carried out on a provisional injection mold due to non-possession of the mold cavity in the shape of Archimedes spiral. Weight of samples and injection pressure were observed in dependence to the percentage of moisture content in granulate

Measuring of emissivity of wet and dry surfaces
Brzobohatý, Tomáš ; Janotková, Eva (referee) ; Pavelek, Milan (advisor)
The objective of this thesis is to create summary of emissivity of wet surfaces, emissivity of rime surfaces and emissivity of dry surfaces. The next objective is to create materials for termovision measurement and find the use for this materials for practice. Theoretical part of thesis deals with a theory of ways of heat transfer (radiation mainly), description of emisivity concept, description of emisivity finding ways and the show emissivity of mesuared materials from avaible sources for working hypothesis. Emissivity of dry, wet and rime samples were measured as the experimental part of thesis. Experimental part of thesis consist of experiment description, working hypothesis, measuring instruments and measuring area description, measuring proces description and presentation of measured results. Obtained dependences are benefits for termovision measurent, energy evaluation and the thermal state microclimate simulations.
