Tubesheet analysis according standards and FEM
Horniak, Patrik ; Vincour, Dušan (referee) ; Pernica, Marek (advisor)
The focus of this master’s thesis is strength design of tube sheet, which is part of shell and tube heat exchanger, with fixed tube sheets. This tube sheet is integrated with both shell and channel of the heat exchanger. First part of the thesis is focused on literature review of shell and tube heat exchangers, tube sheets and calculation standards, which are used for their strength design. The strength design of tube sheet is presented in second part of the thesis, according to the standards: ČSN EN 13445, ASME BPVC VIII and TEMA, along with comparison of these standards. Last section of the thesis deals with the implementation of FEM analysis and its comparison to the analytic approach of strength design, used in accordance to the standards mentioned above.

Software comparison for design and control of pressure vessels
Staňková, Lucie ; Pernica, Marek (referee) ; Lošák, Pavel (advisor)
The main goal of this thesis is to compare different software for pressure vessels design and control. This comparison is done by designing a given pressure vessel, specifically a heat exchanger. The heat exchanger is designed in software Sant’Ambrogio, Visual Vessel Design and PV Elite. Advantages and disadvantages of used software are discussed. Thesis evaluates various aspects of design, particularly graphic interfaces, user-friendliness, clarity and calculated results. The results for the cylindrical shell and the torispherical end of each software are analysed and compared to own calculations based on ČSN EN 13445 design code. Differences among results are explained. Thesis also contains the literature search report of pressure vessels design.

Structural design of an experimental air preheater
Tichý, Jiří ; Skryja, Pavel (referee) ; Jegla, Zdeněk (advisor)
The thesis is focused on structural design of unconventional experimental combustion air preheater into drawing documentation needed for production and realization. Strength and expansion control of exposed elements of construction is also included in the thesis. The final design is obtained by gradual specification of pre-designed and strength and expansion controlled elements of construction. The work also includes discussion of structural properties of the final design.

Structural design of the high-pressure separator with focus on the flange connection
Šmarda, Radek ; Klučka, Ivan (referee) ; Lošák, Pavel (advisor)
The first part of the diploma thesis deals with research in the field of design of process apparatuses. The research continues describing the function, division and main parts of separators. The research part ends with a more detail overview of flange connections. The second part deals with the design and control calculations of the separator using ČSN EN 13445-3 with tightness-strength calculation of the main flange join using ČSN EN 1591-1. At the end of the second part, partial calculations are performed using finite element method in the ANSYS Workbench R2 program, which aim to verify the required tightness of the joint and describe the effect of the bolts tightening procedure on the gasket.

Design of a two-phase separator
Brančan, Peter ; Pernica, Marek (referee) ; Létal, Tomáš (advisor)
Design of a two-phase separator according to the model assignment for separation of natural gas and crude oil. Material selection and checkup for functionality on this process equipment. Emphasis is on selection of dimensions according to mathematical model of mixture sepation. Design is also considering safety of the vessel. Dimensions of separator are optimalized to the lowest possible price of a vessel, while maintaining functionality and required safety of a pressure vessel. Separator is designed according to the standart ČSN EN 13445. Iteretion programs in computational software MATLAB were created to make calculations easier. Programs were created for calculations of separator’s dimensions, nozzles and their reinforcing pads, checking calculations of the vessel and its nozzles and calculations of flanges.

Complex strength design of condenser
Denk, Jakub ; Naď, Martin (referee) ; Lošák, Pavel (advisor)
This diploma thesis focuses on strength design of steam condenser. The goal of the thesis is to make strength calculations for the specific operation conditions, introduce possible solutions, provide recommendations and refer to weak points of such calculation procedures. First, thermal-hydraulic design in HTRI software is performed. Strength calculations respect ČSN EN 13445 standard. Strength calculation with imported temperature field is performed in ANSYS Workbench software. In the next step, another strength calculation is realized in Sant´ Ambrogio software. Results are evaluated in conclusion chapter, including recommendations for the possible following work.

Software Aided Design and Assessment of Shell and Tube Heat Exchangers
Létal, Tomáš ; Klemeš,, Jiří (referee) ; Vincour, Dušan (referee) ; Jegla, Zdeněk (advisor)
Subject of this work is a development of an integrated software environment for mechanical design and check of shell and tube heat exchangers. Processes of mechanical design and checks well as software which perform these processes are broken down to basic methods and parts. Mechanical design is usually performed according to some standards. In this work, ČSN EN 13445 is used. This standard describes mostly design check calculations which can be easily algorithmized. On the contrary, design calculations are described to some extent in few simple cases and mechanical design of shell and tube heat exchanger has not been fully algorithmized yet. Subject of this work is design of software, which will be capable of automatically performing mechanical design from datasheet as an input. Based on breakdown of design and check processes, requirements for key software features are derived. Important part of presented work is design and implementation of key modules – data model of shell and tube heat exchanger, module for mechanical design check according to ČSN EN 13445. These modules form basis of the software which will be developed further in future work.

Design of heat exchanger chamber
Horník, Jan ; Naď, Martin (referee) ; Klučka, Ivan (advisor)
The master thesis is focused on the field of heat exchangers. Theoretical part makes the reader familiar with heat exchangers. Practical part is focused on design of chamber, which is part of heat exchanger. Practical part consists of strength calculation by standard ČSN EN 13445. Dimensions of tube sheet are gained in program Visual vessel design. Those parameters are used for creating of 3D model with accurate dimensions which is analyzed in ANSYS Workbench. Output of this analysis is evaluation by stress classification. Practical part is supplemented by drawing of heat exchanger.
