Assessment effects substandard tributaries flowing a proportion on Q/h characteristics thin-plate weir with a rectangular cutout
Šmidrkalová, Nina ; Šafář, Robert (referee) ; Žoužela, Michal (advisor)
This master´s thesis deals with the problem of measuring flow, especially using the method of Q/H characteristics. It describes the thin-plate weir and mentions specific channels. The master´s thesis suggests options of monitoring flow capacity in fixed proffiles with free surface. The master´s thesis also includes an experiment, which is focused on simulation of substandard tributary flowing proportions before weirs for determining their effect on Q/H characteristcs. The experiment is carried out on a thin-plate weir with a rectangular notch at the Department of Water Structures at the Faculty of Civil Engeneering in Brno. Another part of the master´s thesis is data processing to get an idea about the impact of the phenomenon in real applications. Finally, options are recommended for follow-up research.

Flow measurement
Pátek, Tomáš ; Kunz, Jan (referee) ; Beneš, Petr (advisor)
This bachelor thesis deals with thermal flowmeter design. In the theoretical part are briefly described flow types, general formulas of fluid mechanics and different flow measurements methods. Second practical part this bachelor thesis deals with design of thermoanemometric gas flow sensor with FS7 sensor by IST AG. Design is based on many measurementrs to get basic features of sensor IST FS7 like heater warming depending on flow, heat transfer in zero flow and basic characteristic. Based on measurements, it is designed mathematical model of sensor by two methods. So it is designed universal performing electronics, which can be used with IST FS7 or IST DFOOL sensors. It is based on development kit Texas Instrumens MSP-EXP430FR2311. Firmware and MATLAB script which processing measured data is included.

Formula Student Engine Oil System Function Analysis
Liška, David ; Janoušek, Michal (referee) ; Ramík, Pavel (advisor)
This thesis deals with the analysis of the used lubrication system on the eighth generation of Dragon 8 car from team TU Brno Racing. In the beginning of the thesis there is clarifying the Formula Student competition, in which the student team participates, explains its rules and limitations affecting the combustion engine lubrication system. Furthermore, the thesis deals with the possibilities of oil cooling systems and the search of the used components in lubrication system. For the lubrication system is calculated the theoretical volumetric flow rate by an oil pump and then it is verified by measuring the actual flow rate required to determine the cooling capacity of the oil cooler.

The determination of minimal countercurrent distance of the water surface sensor from the thin-plate V-notch weir.
Kopečná, Monika ; Zubík, Pavel (referee) ; Žoužela, Michal (advisor)
This thesis clarifies the issue of the measuring flows with the help of capacity measurement systems using Q/h characteristics and also describes measuring techniques for determining the water surface level. The various types of measuring weirs and their Q/h characteristics are described in detail. It also mentions the position of the installation of the sensor. The main task is to find a practical minimal countercurrent distance of the water surface sensors used in practice for use with a V-notch weir in the form of experimental measurements in the water management research laboratory at the Department of Water Structures Faculty of Civil Engineering in Brno. The weirs used for this experiment had top angle cutouts of 90°, 53°8´ and 28°4´. The obtained data is evaluated and subsequently the minimal countercurrent distance of the water surface sensor is determined. The thesis also includes recommendations for further research.
