Economic view of the fast closing valve selection for HPP Vranov
Gipka, Ondřej ; Kuchař, Jan (referee) ; Klas, Roman (advisor)
The thesis deals with the evaluation of the investment in the fast closing valve replacement in The dam Vranov using Computational fluid dynamics (CFD). The final effects of the fast closing valve replacement will be examined on three different types of valves with regard to the turbine output in operation zone and without the influence of water intake runner and turbine draft tube. The aim of the thesis is to theoretically evaluate alternatives of the fast closing valve replacement and define its basic characteristics and classifications.

Design of gas spring
Machů, Tomáš ; Kuchař, Jan (referee) ; Pochylý, František (advisor)
The bachelor thesis deals with springs, which elastic medium is compressible fluid. The individual types of springs and their usage in the technical practice are presented in this work. Below the work deals with mathematical model and development of new type of gas spring.
