Design of separator
Benda, David ; Nekvasil, Richard (referee) ; Lošák, Petr (advisor)
This diploma thesis deals with design of the gas separator according to the standard ČSN EN 13445. The design is based on the specified operating parameters and the basic dimensions, including the individual positions of the connecting flanges on the device according to the relevant schema. The assignment also includes the load of the nozzles from connected pipelines to the device. The analytical calculation of the design is performed in the commercial software NextGen with the analysis of the individual components used. Furthermore, some parts of the device are inspected in detail using the finite element method in the commercial software Ansys. The thesis also included the drawing documentation of the designed gas separator.

Structural design of heat exchanger pair
Pernica, Marek ; Buzík, Jiří (referee) ; Naď, Martin (advisor)
This master’s thesis deals with structural design of twin heat exchanger with vertically stacked horizontal vessels according to CSN EN 13 445 standard. Brief introduction and basic characteristics of shell and tube heat exchangers is performed in the beginning part of the thesis. Design of the heat exchanger was initially performed using design by formula (DBF), which was verified by specialized software Sant´Ambrogio. Since this approach does not include methods for assessment of the nonstandard connection between the vessels, simulations of significant load states were performed using FEM analyses followed by result evaluation using stress categories.

Design of high-pressure heat exchanger
Marada, Petr ; Kilkovský, Bohuslav (referee) ; Jegla, Zdeněk (advisor)
The aim of the thesis is to design a heat exchanger for heating natural gas in the mining process and subsequent treatment. The first part describes natural gas itself, its origin, mining and ways of treatment. There are described technologies used for finding the deposits itself or processes by which water, sulfur and solid particles are removed from the extracted gas. The next section deals with the types of heat exchangers most commonly used in industry. There are also described basic relations for heat-hydraulic calculation of heat exchanger. In the practical part the heat exchanger itself was designed. World-wide HTRI software was used for the heat-hydraulic calculation and for strength calculation according to the standard ČSN EN 13445 was used sofware Sant´ Ambrogio.

Design of heat exchanger
Buzík, Jiří ; Lošák, Pavel (referee) ; Nekvasil, Richard (advisor)
The master thesis deals with thermal hydraulic design and strength design of a heat exchanger with “U” tube bundle inside of a shell. The first chapter introduces general design issues of the heat exchangers. The following chapter describes thermal hydraulic design created in software Maple 16.0 by using Kern’s method and the method of Bell-Delaware. HTRI software was used for the control of thermal hydraulic design correctness. To check critical locations of fluid flow in space between the tubes, the CFD model was created at ANSYS Fluent 14.0 software. Accuracy of strength design was verifying by Sant’ Ambrogio software in accordance with ČSN EN 13 445 standards. The last chapter concerns with FEM analysis. According to standards ČSN EN 13 445 the design by analysis namely method based on stress categories were used for the strength analysis of nozzle.

Design of autoclave
Poduška, Libor ; Létal, Tomáš (referee) ; Nekvasil, Richard (advisor)
Master thesis deals with general basic design od autoclaves. It deals with the design of an optimal design solution autoclave to set parameters with the design requirement of hermetic doors for loading the workpiece. This solution is analyzed regard to stable pressure vessels. The whole design is processed in parametric SolidWorks software with which they are executed and initial stress analysis of individual designs. Final strength FEM analysis is performed using Ansys. Some proposals are technical-economic evaluation.

Strength calculation of heat exchanger tubesheet with focusing on economic evaluation
Horniak, Patrik ; Vincour, Dušan (referee) ; Buzík, Jiří (advisor)
This bachelor thesis is focused on strength design of assigned shell-and-tube heat exchanger. This heat exchanger have fixed tube sheets and straight tubes. Designed tube sheet is integrated with shell and flanged to the channel. First part of the thesis serves as introduction on the issue of heat exchangers and tube sheets. Following chapters are dedicated to the strength design of tube sheet thickness based on the ČSN EN 13 445 standard. These chapters are dealing with input parameters, basic requirements of calculation, equations essential for calculation of stress in heat exchanger and analysis of stresses in heat exchanger with the use of proper strength conditions. Conclusion of these chapters is evaluation of calculated results from personal scipt written in Python language using Spyder environment. Correctness of these results is ensured by their comparison with the output of Visual Vessel Design (VVD) program. Final part of the thesis is economic evaluation of whole tube sheet design based on possibility of choosing different analyzed material.
