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.

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.
