Design of heat exchanger for feeding heat water network 5,5 MW
Kubíček, Ondřej ; Moskalík, Jiří (referee) ; Baláš, Marek (advisor)
The Master thesis deals with the water-heater design for heat-exchange station with total power output 5,5 MW. The goal of the thesis is to make thermal and hydraulic calculation in the extent of the assignment and to develop a projection drawing of the heater along with a correct dimensioning of the shell and flanges. Thesis goals were met according to the assignment. The introductory part of the thesis briefly introduces to the heat-exchanger problematic and selected topics about heat-transfer. Following the basic mass and energy flows calculation inside the heater together with the thermal and hydraulic design determines the size of the heat transfer surface of pipes. After that the design calculations were made, whose results are used to determine the basic dimensions of selected parts and checking the accuracy of designed dimensions. In the last part of the work the design process is more described also with a more detailed description of selected parts.

Checking of heat exchanger to flow-induced vibration
Mazura, František ; Pernica, Marek (referee) ; Buzík, Jiří (advisor)
This bachelor thesis focuses on the thermal-hydraulic design of the heat exchanger and flow induced vibrations checking. The introductory part describes the basic distribution and function of heat exchangers. The next part introduces the thermal-hydraulic design in the Python programming language using the Kern‘s method for an U-tube heat exchanger. Thermal-hydraulic design outputs are compared with values from HTRI software. Subsequently, the issue of the flow induced vibrations is characterized and the checking of these vibrations according to the normalized TEMA standard is performed. Finally, the heat exchanger is checked using the Poddar & Polley graphical method.
