Analysis of heat exchanger troubles
Bartošek, Nikola ; Jegla, Zdeněk (referee) ; Kilkovský, Bohuslav (advisor)
The master thesis is focused on analysis of specific cross-flow in-line tube bundle heat exchanger which deals with significant operational problems. Thermal, hydraulic and vibration calculation analysis of selected parts of the heat exchanger is performed based on CFD flow distribution results. Calculation is performed by using Maple software. Thermal and hydraulic calculations are compared with results obtained by commercial software HTRI.

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.

Software support in creating a complex calculation tool
Zich, Jan ; Jegla, Zdeněk (referee) ; Kilkovský, Bohuslav (advisor)
The master’s thesis is focused on the calculation of a heat exchanger with a crossflowed tube bundle found most in the air-cooled heat exchangers. The knowledge gained from the literature search is used to create libraries, giving a choice of several different methods in the hydraulic and thermal calculation as well as other key areas. These libraries allow their implementation in the comprehensive computational software P.E.C. developed at the Institute of Process Engineering. The thesis includes a verification of the correctness of the library’s calculations with showcased problems as well as 2 parametric studies. These investigate the dependencies of the transverse and longitudinal pitch on some of the process parameters of the heat exchanger.

Calculation methods for tube banks heat exchanger
Housírek, Jiří ; Jegla, Zdeněk (referee) ; Kilkovský, Bohuslav (advisor)
This diploma thesis deals with calculation methods of heat exchanger with cross-flow tube bundle. The first part of the thesis contains summary of generally known basic calculation relations used in calculations of heat exchangers and a detailed description of a given heat exchanger.The second part of the thesis provides a description of available calculation methods of a given aparatus required for its thermal and hydraulic calculation. The final part describes application POST in 1.0 which has been formed on the basis of these calculation methods. Using this application check calculation of exchanger with cross-flow tube bundle was carried out and gained figures compared with results gained by means of professional calculation program HTRI.
