Thermal-hydraulic calculation and stress analysis of a heat exchanger
Fiala, Petr ; Létal, Tomáš (referee) ; Nekvasil, Richard (advisor)
Main object of the work is stress analysis of specific parts of tube and shell heat exchanger by using MKP. Each part is judged by two different computation methods. The method based on computation values and the method nearing real condition of operation of device. To approach real load are in the work made basic heat transfer computations for entire device and for analyzed part are computed boundary conductance by using CFD.

Principles and design of project elaboration of boiler islands aimed at piping
Suchomel, Radoslav ; Létal, Tomáš (referee) ; Nekvasil, Richard (advisor)
The Thesis solves the issue of a design and construction of piping specifically focused on boiler apparatus and its equipment. This issue is important for creation of the piping classes in the (PDMS) programmes and for acceleration of output parameters which are mainly the temperature, materials, variable parameters, etc. This leads to other problems such as service life, security, economy, etc., are.

Optimum design selection of a cryogenic tank
Létal, Tomáš ; Gottvald, Jakub (referee) ; Nekvasil, Richard (advisor)
The purpose of this work is to find optimal design for mounting cryogenic tank into ISO container frame. Solution is based on stress analyses of several designs and theirs interpretation. According to standards, set of tests, which all cryogenic containers have to pass before being put into operation, is created. Designs are tested by final element method using software ANSYS. At first, results of the stress analyses provide base for improvements targeted to better meeting with needs of the standards. In final stage, the results participate in optimum design selection.

Flange design software according to ČSN EN 13445
Schütz, Stanislav ; Lošák, Pavel (referee) ; Létal, Tomáš (advisor)
The goal of this work is to create a simple portable software for stress analysis of gasketed flange connections according to ČSN EN 13445 - Unfired pressure vessels. The programming language Python was chosen for the programming and the program was created in IDE called Eclipse. The thesis includes: literature search in order to get some insight into the theme of stress calculations of flanges, a description of the strength calculation according to the Standard mentioned above and a description of the created program including its debugging. The main output is software called Imhotep. It comes in two forms – as a module executable via Python and a portable .exe version.

Design of storage tank
Jahodová, Miroslava ; Lošák, Pavel (referee) ; Létal, Tomáš (advisor)
Subject of this bachelor thesis is a structural design of a vertical cylindrical storage tank with fixed roof. In the first part, basic types of storage tanks are described, followed by various approaches to structural design of a vertical cylindrical storage tank. Second part includes design calculations of the vertical cylindrical storage tank according to the standard ČSN EN 1993-4-2 as well as stress analysis using finite element method.

Design of container for bulk transport
Cihlář, Milan ; Lošák, Pavel (referee) ; Létal, Tomáš (advisor)
The topic of this work is industrial usage of ISO containers and their classify. Other part is about construction a stress analyses of container type 1C (length is 20 feet) which is used to a bulk transport. The software Ansys was used to stress analyses. In this analyses was used only simply model which don´t have filling and emptying aperture etc. In results was controlled maximum stress in the all elements.

Check calculation of parts of the pressure vessel
Bukal, Oldřich ; Lošák, Pavel (referee) ; Létal, Tomáš (advisor)
Pressure vessels play irreplaceable role in different branches of industry. From the perspective of pressure vessel construction high reliability and safety are required. This bachelor thesis is focused on control calculation of the basic parts of a vessel according to the standard ČSN EN 13445-3 including FEM analysis followed by stress categorization.
