Modern technological elements for tubular heat exchangers
Plánková, Tereza ; Babička Fialová, Dominika (referee) ; Jegla, Zdeněk (advisor)
The aim of this diploma thesis is to get acquainted with modern technological elements currently used in shell-and-tube heat exchanger in the shell-side and tube-side, thermal-hydraulic calculation of selected elements and comparison of thermal-hydraulic properties with classically used competing technological elements. The work deals mainly with EM baffle in the tube-side and tube inserts like the twisted tape type (and its modifications) and coiled wire in the tube-side. The theoretical part is focused on acquaintance with classical technological elements in shell-and-tube heat exchanger and with basic thermal-hydraulic calculations, practical part then on acquaintance with modern elements and thermal-hydraulic calculation of selected elements. These calculations are then compared with the results of the thermo-hydraulic calculation of similar elements.

Heat recovery from melting furnace waste gases
Dobai, Szabolcs ; Hejčík, Jiří (referee) ; Jaroš, Michal (advisor)
This master’s thesis deals with the design of heat recovery system from melting furnace waste gases. The first part is devoted to a brief description of heat exchangers, with the special importance being placed on the shell-and-tube heat exchanger. The second part contains a calculation of stoichiometric combustion, design of geometrical dimensions, calculation of pressure drops and power. At the end of the thesis there are various possibilities of utilization of the obtained waste heat and their basic economic assessment.

Prediction of fluids temperature profiles in heat exchanger
Havelková, Pavla ; Kilkovský, Bohuslav (referee) ; Jegla, Zdeněk (advisor)
This master’s thesis is focused on the description and processing of the cell method, which is generally recommended for prediction of fluids temperature profiles in heat exchanger. In the thesis the basic equations for calculating heat transfer are presented and is also described the current situation in the field of computational prediction of fluids temperature profiles in heat exchangers. The cell method is solved by using the software Maple and is applied to the specific case of industrial heat exchangers. The results obtained by the cell method are compared with the results obtained by educational version of software HTRI Xchanger Suite. By this comparison explicitness of the cell method is assessed.
