It is an education combining solid theoretical foundations in applied mechanics, design of power machines, design and operation of power systems, knowledge and skills in computational and experimental modelling in the field of power engineering and applied fluid mechanics and thermomechanics.
In the case of applicants from other faculties or universities, it is necessary that they master the above-mentioned disciplines at the level taught in these programmes.

1. New approach to verification of guaranteed parameters of large hydropower plants.

   Nowadays, the verification of guaranteed parameters of large hydropower plants is based primarily on the IEC 41:1991 standard. The procedures described in this standard are obsolete. Actually, topical measurements are carried out in accordance with this standard, but procedure and measuring techniques differ significantly from this standard. The result of this doctoral thesis will be new approach and procedure for measurement and evaluation applicable to large hydropower plants.

2. Augmentation of convective heat transfer due to vapor condensation in gas-vapor fluid flows.

   Vapor condensation in case of gas-vapor heat transfer fluids increases the intensity of convective heat transfer. The PhD thesis will aim at the study of this phenomenon, in particular with respect to moisture condensation in heat exchangers with moist air as the heat transfer fluid.

   Tutor: Charvát Pavel, doc. Ing., Ph.D.

3. Computational modeling of heat transfer in the boundary layer of heat exchangers

   The subject of the study is the issue of numerical modeling of heat transfer with a focus on the mathematical description of transfer in the boundary layer at the wall of heat exchangers. The solution will include a summary of the approaches used, testing their use in specific configurations and formulating a more accurate description based on validation measurements.

   Tutor: Pospíšil Jiří, prof. Ing., Ph.D.

4. Development of a balloon burner

   The subject of the study is an atmospheric gas multi-jet burner used for balloon flying. These burners have been developing slowly for decades and the old and proven concept today does not meet the requirements for a comfortable flight. The problem areas are in particular: to reduce water condensate from the air on the fuel exchanger tubes, black flame burnout, poor air access, Radiant heat reduction, flame geometry requirements with respect to the application, Noise reduction These are a number of conflicting requirements that require a systematic approach and a sufficient understanding of the problem. The work will include a theoretical analysis and create a mathematical-physical model of processes, including experimental verification (description, system identification) and modeled first one burner segment), later or the entire burner. Experimental and mainly simulation methods will be used in the development. The doctoral student has a task - describe phenomenologically relevant phenomena, quantify relevant quantities (by measurement, calculation) - propose promising solutions with regard to efficiency and technical, economic, legislative and other constraints. The topic has full technical and material support, especially laboratory equipment, technology and material for experiments. Partial financial support of the student from the project is expected. The topic is related to one or more existing or submitted projects and is solved in cooperation with the company BALÓNY KUBÍCEK spol. s r.o. It is assumed that several months of internship abroad, participation in technical seminars and presentations at conferences.

5. Development of advanced spray solutions for CO2 capture

   Separation and gas cleaning applications that are based on liquid sorbents rely on efficient mass transfer in gas-liquid contactors. Liquid atomization is frequent method of increasing the interfacial area in processes where mechanical, thermal or chemical interaction of the liquid with surrounding gas takes place. Several atomizer types (pressure-swirl and twin-fluid atomizers, multi-nozzle plate, or flat-jet arrays) have been proposed and installed in spray towers particularly for CO2 capture with absorption using alkanolamine solutions and aqueous ammonia. The maximization of the interfacial area is the universal primary requirement in gas–liquid absorptive mass transfer operations. For spray scrubbing, the atomizer should produce a uniform spray with drop diameters small enough to generate large interfacial area and at the same time large enough to prevent excessive entrainment. The available literature does not answer what spraying methods suits these aspects best. Several strategies will be studied for uniform film/droplets production and mass transfer enhancement between gas and liquid phases. The main target will be reduction of the spray polydispersisty with selection of the most competitive atomization technique and its further development in line with modification of liquid rheology (non-Newtonian liquids, organic additives). Enhancement of the turbulent mixing process via external field force (ultrasonic irradiation induction, vortex flow in the spray tower) are additional options. Sensitivity of the CO2 capture process to the above aspects will be studied. The topic has full technical and material support, especially laboratory equipment, technology and material for experiments. Partial financial support of the student from the project is expected. The topic is related to an existing or submitted project. The possibility of several months of internship abroad, participation in technical seminars and presentations at conferences is expected.

6. Improving the energy efficiency of the heat pump and refrigeration cycles with the use of phase change materials (PCM)

   The aim is to explore the possibilities of using PCMs in the vapor-compression cycles of heat pumps and refrigeration systems in order to increase the energy efficiency of their operating cycles. The possibilities of integrating PCM-based thermal energy storage in the vapor-compression cycles will be explored by computer simulations. The best solutions will be validated experimentally on a lab-scale vapor-compression refrigeration system.

   Tutor: Charvát Pavel, doc. Ing., Ph.D.

7. Interference of the oscillating body and the pulsating fluid.

   In the interior of hydraulic machines there is vibration of mechanical parts and pressure pulsations in the flowing fluid. These two phenomena can not be separated from one another and must be solved together. At present, there is a frequent approach to determining additional fluid spills in mechanical parts. Methodology for determining these properties will be developed.

   Tutor: Habán Vladimír, doc. Ing., Ph.D.

8. Preparation and combustion of liquid fuels in the combustion chambers of turbine engines

   The energy requirements of aircraft propulsion will for a long time require high-energy-density resources, ie especially turbine propulsion. The growing demands on the ecology, economics of operation and performance parameters require the continuous development of these devices, better understanding and advanced control of the processes that affect their function. At the workplace, we have long been engaged in research and development of nozzles for spraying aviation fuels into the combustion chambers of turbine engines. After solving the design of the nozzles themselves and the mechanical interaction of the spray with the surrounding gas, it is necessary to deal with other phases of the process, ie fuel evaporation and combustion, including modern trends in turbo engines. The current ambition is to create a workplace that will enable this research and development of advanced jet engines. The doctoral student will solve the preparation of the test equipment, perform experiments on it using modern optical diagnostics and in combination with CFD simulations will contribute to a better understanding of relevant processes. The topic has full technical and material support, especially laboratory equipment, technology and material for experiments. Partial financial support of the student from the project is expected. The topic is related to one or more existing or submitted projects and is addressed in cooperation with PBS Velká Bíteš. The possibility of a several-month internship abroad, participation in technical seminars and presentations at conferences is expected.
