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 exchangers for high temperature applications
Jonák, Martin ; Kilkovský, Bohuslav (referee) ; Kermes, Vít (advisor)
This thesis is devoted to thermal-hydraulic design and rating of heat exchangers with the specialized commercial software HTRI. These heat exchangers are solved for real high-temperature applications, where the hot fluid is a flue gas with high temperature (above 500 °C). In the thesis is made a brief analysis of the conventional design of heat exchangers usable for high-temperature aplications, description of the basic relations, description and brief user manual of software HTRI. Further, work includes a comparative study of methods for calculation of pressure drop of the fluid at 180° elbows, as support analysis for solution of required applications characterized by low pressure drop of process fluids.

Calculation algorithms for thermal-hydraulic design and rating of unconventional heat transfer equipment
Mikeška, Petr ; Kohoutek, Josef (referee) ; Jegla, Zdeněk (advisor)
The aim of diploma thesis is creating calculation algorithms off single types unconventional heat transfer equipment and their aplication in thermal - hydraulic calculations in the industrial aplication . The main attention is paid to shell and tube heat exchangers with ROD and disc baffle system and radiation heat exchanger. All of these exchangers are used mainly in process of waste thermic destruction. The theoretical part of the work describes construction details of each heat exchanger and calculation algorithms of these equipments. The practical part of the work applies theoretic calculation alghortims in the industrial aplication which is design and rating. In the final part advantages and disadvantages of results have been assessed for construction and process aspects.

Intermediate heat exchanger natrium - natrium
Kupčík, Petr ; Martinec, Jiří (referee) ; Šen, Hugo (advisor)
This paper deals with intermediate heat exchangers in nuclear power plants. First section of this paper is devoted to analysis and divide of construction designs of intermediate heat exchangers in commercial and experimental power plants. There is a description of thermal, hydraulic and strength calculations during projection of IHX in the second chapter. There has been made a blueprint of loop type IHX in the final chapter of this paper.
