Issued topics of Doctoral Study Program
The theme refers to the continuous transmission of rotary motion mechanisms that serve to facilitate a particularly economical drive vehicles, such as passenger cars, trucks, trolleys, trams, locomotives, etc. It is particularly timely for hybrids, electric cars, etc. It is assumed theoretical solution of the energy flow the branches, prototype production and confirmation of the chosen means of transport. Promised cooperation with companies ZMS VRS Institute of motor vehicles in Prague, EM Brno.
Supervisor: Veselka František, doc. Ing., CSc.
The work is aimed to theoretical principles and phenomena in non-standard installations of high voltage equipment. Theoretical descriptions of both physical and mathematical models will be applied to testing equipment and accessories for impulse tests of switchgear and electrical devices. Attention will be devoted to specific cases of dynamic tests of electrical apparatus and machines. Results of simulations will be evaluated in both diferential and integral quantities for verification with experimental measurements.
Supervisor: Fiala Pavel, prof. Ing., Ph.D.
Influence of individual parts of a low voltage circuit breaker on the proces of switching arc quenching will be studied. A combination of experimental methods together with numerical methods will be used for an identification of dominant factors. The main aim is to createa comprehensive description of the quenching process which will serve as a tool for development and/or inovations of new types of switchgear.
Supervisor: Aubrecht Vladimír, prof. RNDr., CSc.
The theme is focused on the measurement of very small distances and deformation of rotating electrical parts. machines that have a significant effect on the operating characteristics of machines and equipment. The measurement is made modern measuring, recording and evaluation techniques. The aim is to assess and optimize the partial impacts of physical quantities on the characteristics and parameters of electromechanical systems. The work consists of theoretical, experimental and practical part. The issue is UVEE continuously addressed in the grant project, forthcoming international cooperation. Results are regularly published.
Based on requirements for contact materials, suitable contact materials will be investigated in various switchgear design. Consequently, the selected materials will be analyzed in detail in order to find cruciable quantities involved in numeric simulations of switchgear behavior with the contact connection taken into account (electrical and thermal resistances, ..).
Solution of energy balance in an arc plasma with respect to the radiative heat transfer. Influence of various spectral intervals and various molecular species on the radiative heat transfer in the arc plasma. Development of computer code for calculation of absorption coefficients of given thermal plasmas.
Small and medium sized modular reactors have recently been the projects of special interests of some nuclear specialists and technical public. Such projects are primary designed for distant areas with difficult access and limited grid connections possibilities. However, small modular reactors might be utilized in developed countries too; they can serve as locally distributed low-cost base-load sources. Safety systems of small modular reactors are based on passive systems and physical phenomena. Goal of dissertation project is to propose, to design, and to develop the dynamic model of small modular reactor system and to analyze it - not only during severe accident conditions but especially during abnormal operation transients. These have not been sufficiently investigated and experienced yet.
Supervisor: Katovský Karel, prof. Ing., Ph.D.
Goal of proposed dissertation project is to develop an complex simulation model for safety, reliability, and efficiency operation of new design of nuclear fuel. Model will be validated using experimental data from research reactor measurements. Investigation will be perforem within the cooperation with UJV Rez and CV Rez.
The theme includes issues of sliding contact in high-end applications of electromechanical systems operating in dynamic operating conditions (Starting, regulation, etc.) with high ratings of current, voltage, speed, power, speed, and defined the parameters of the surrounding environment. Since the development of electromechanical systems in particular is currently associated with a requirement for high reliability and durability as defined, should be to extend the life of work sliding contact, reducing degradation of the stationary and moving parts of the sliding contact, eliminating the influence of the surroundings on the current flow between the stationary and moving part of the sliding contact. Partial information will be obtained during the analysis and field current.
The theme includes a study of the issue of sliding contact, not only in traditional applications, but also in special applications of electromechanical systems operating in dynamic operating conditions with high rated current, voltage, speed, velocity and defined parameters of the environment. In the case of sliding contact is expected to use newly developed materials such as HS22196, VS3110. This concept is the integration of the sliding contact with the application of Teflon and the sliding contact of carbon - carbon bonds. Promised cooperation with companies ElringKlinger Kunstofftechnik GmbH, NAREX, EM Brno.
The theme is focused on the application of nanotechnology in electrical machines, particularly with a sliding contact. The work builds on the extensive knowledge and skills in this area, which were obtained on UVEE FEEC in the application of modern technology in the design of electrical machines. The aim is to identify the dependencies and relationships between components in different design and application version with a link such as EMC .. The problem is solved UVEE continuously and is achieved interesting results published on an international level. The Institute has a special measuring workplaces for practical verification of theoretical assumptions and cooperates with leading companies.
