Heat-Hydraulic Design of the Exchanger for the Test Device
Únar, Jan ; Toman, Filip (referee) ; Kracík, Petr (advisor)
This bachelor thesis deals with the design of tube exchanger for testing device. The exchanger will serve to heat or cool the flowing air to the desired value. The heating / cooling medium flowing in the tubular space is water. The first part describes the functions, distribution, requirements and current trends of heat exchangers. The second part consists of thermal and hydraulic calculations for the variant of bare tubes and finned tubes and evaluation of results. The result of this work is a design of a tube exchanger, which has the shape of a square type channel for both variants.

Assessment of geometric accuracy of machining center using digital inclinometers
Únar, Jan ; Marek, Tomáš (referee) ; Holub, Michal (advisor)
This diploma thesis deals with assessment of geometric accuracy of machining center MCV 754 QUICK. BlueSYSTEM digital inclinometers from WYLER AG, XL-80 laser interferometer from RENISHAW, Ballbar QC20-W from RENISHAW and LaserTRACER self-guiding laser interferometer from ETALON AG were used to measure accuracy. Error of the X straightness in the direction of the Z axis was assessed. The first part of the paper describes the geometric accuracy of the machine, currently available instruments for measuring geometric accuracy and an explanation of straightness. The second part consists of the design of measurements, experiment, evaluation and comparison of results and recommendations for teaching.
