Selection of suitable fluid flow directions in laminar flow tubular cooler
Krobot, David ; Kohoutek, Josef (referee) ; Jegla, Zdeněk (advisor)
This master’s thesis is devoted to problematic of selection of suitable flow directions in double pipe heat exchanger. First chapter is oriented to the construction of tube heat exchangers. It is also discussed impact of construction solution to the flow character and changing of his process parameters. The difference between parallel and countercurrent flow is also occurred in this parts. The next chapter is focused to the basics of heat-hydraulic calculations of heat exchanger. This also means explanation of ways of heat transfer and heat exchanger function. There are told about specific access to the solving problem of fluid laminar flow. The third chapter is detailed focused to the calculating of heat exchanger. At first is discussed factors, which have impact to the flow character. Next are detailed descriptions of design and controlling calculations, including more alternative ways to solve it. Next chapter exploit those results for deciding, which flow arrangement will be better for given case. Last chapter contain realization and reformulating of process heat exchanger calculating to the program code in Maple. There is also description of used algorithms and operating with them, so any user could be able to work with it. In this master’s thesis are used many examples from attached programs on different parts.

Analysis of heat losses of operated heat exchangers
Sýs, Tomáš ; Babička Fialová, Dominika (referee) ; Jegla, Zdeněk (advisor)
The proposed bachelor’s thesis deals with calculation and analysis of heat losses of operated heat exchangers used for food applications. In the first part of the thesis, general problematics of heat exchangers is introduced, including their use and breakdown by basic categories, as well as problematics of insulation, which is supplemented by a list of the most commonly used types of insulation. Another chapter is devoted both to the assignment and description of the industrial case; drawing documentation and measured input data necessary for the calculation of heat losses are also presented. The last part of the thesis introduces the used method of assessment of heat losses of the heat exchanger network, achieved results and their discussion.
