Relation between forces induced by fluid flow and dissipative processes in boundary layers
 Mináriková, Petra ; Maršík, František (advisor) ; Lanzendörfer, Martin (referee)
Práce se zabývá vlivem disipativních proces· v mezních vrstvách, konkrétně vlivem viskozity tekutiny a dále vlivem difúze vodní páry ve vzduchu na vznik sil p·sobících na obtékaná tělesa. Z Croccovy věty plyne, že gradient entropie má sv·j podíl na vzniku cirkulace a d·sledkem toho i na vznik vztlakové síly. Práce zkoumá vznik vztlakové síly při obtékání rotujícího válce, v soft- waru FEniCS modeluje tuto situaci, porovnává s modelem nevazké nestlačitelné tekutiny a následně i s experimentem provedeným Ing. Zdeňkem Trávníčkem a Ing. Zuzanou Broučkovou. Taktéž zkoumá vznik vztlakové síly při vypařování na horní straně válce a srovnává s případem rotujícího válce. 1

Design of Passenger Car Wheel
 Kapoun, Lukáš ; Porteš, Petr (referee) ; Hejtmánek, Petr (advisor)
The present master thesis deals with the design of wheel disk for passenger car. The review part of this thesis summaries the history and development of the wheel; this is followed by a description of individual construction types of wheel disk for passenger car presently used. The construction part of this thesis provides a design of disk of given parameters based on the analysis of forces acting on the car wheel. For the purposes of design, the stress and fatigue analyses are performed.

Hydraulic and mechanical holding device of front shovel of excavator LB 115
 Bělov, Pavel ; Lžičař, Roman (referee) ; Škopán, Miroslav (advisor)
This Diploma thesis solves a quick coupler design for a loader. In introduction of the Diploma thesis are mentioned two potential designes and convenient solutions. Subsequently are outlined two practicable designes of a quick coupler for a original bucket, as a data componant of the second construction design is enclosed basic strength calculation. The ending point of the thesis deals and compare with the force decrease in use of a quick coupler and appraisals achieved ascertainment.
