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.

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 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.

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 heat exchanger after ČSN EN 13 445
Lošák, Pavel ; Vincour, Dušan (referee) ; Vincour, Dušan (referee) ; Nekvasil, Richard (advisor)
Diploma thesis is fucused on strength calculation of the heat exchanger according to ČSN EN 13 445. Introductory part introduce problems with the design of heat exchangers. In other parts there are a strength calculation of the heat exchanger according to ČSN EN 13 445, the results of the analysis with their appreciation. Annexes included output logs from the program Sant 'Ambrogio, and drawings documentation.
