The study programme in Applied Mechanics is focused on the preparation of highly qualified experts with the prerequisites for scientific work, mastering modern computational and experimental methods in the field of body mechanics, including specific areas of mechatronics and biomechanics. The aim of the study is to provide students with the necessary theoretical knowledge and practical experience in the field of mechanics corresponding to the topic of doctoral studies. To achieve the set goals and profile, students complete the subjects prescribed by their Individual Study Plan, which creates a theoretical basis for mastering the topic at the highest level. They then prove their practical mastery of the topic by passing the State Doctoral Examination and preparing and defending the Doctoral Dissertation.

Graduates of the doctoral program Applied Mechanics have highly specialized professional knowledge and competencies, especially in modern computational and experimental methods in the field of applied mechanics, or mechatronics or biomechanics, and their use in research and development in technical and medical. At the same time, it has professional adaptability, which gives great chances for employment in research and development, as well as in the field of technical calculations and managerial positions. This is evidenced by graduates working not only in academia and private research, but also in small computer and software companies, including leadership and management positions in design, computing and development departments or sales offices of international companies. With the penetration of computer modelling and support into the field of medicine, the application of biomechanics can be expected not only in this interdisciplinary sphere of research and development, but also in newly emerging positions of computer support in hospitals and clinical workplaces.

Brno University of Technology acknowledges the need for equal access to higher education. There is no direct or indirect discrimination during the admission procedure or the study period. Students with specific educational needs (learning disabilities, physical and sensory handicap, chronic somatic diseases, autism spectrum disorders, impaired communication abilities, mental illness) can find help and counselling at Lifelong Learning Institute of Brno University of Technology. This issue is dealt with in detail in Rector's Guideline No. 11/2017 "Applicants and Students with Specific Needs at BUT". Furthermore, in Rector's Guideline No 71/2017 "Accommodation and Social Scholarship“ students can find information on a system of social scholarships.

The doctoral study programme in Applied Mechanics is a continuation of the currently accredited follow-up master's study programme in Applied Mechanics and Biomechanics. However, it focuses more generally on graduates of subsequent master's degree programmes in various fields of mechanics and mechatronics, or mathematical, physical or materials engineering, the graduates of which are able to continue in the third stage of study and obtain the scientific degree of Ph.D. demonstrate the ability of scientific work.

1. Compensation foil created by cutting plotter including connecting manifolds

   The concept of a compensation foil was introduced in Heat Transfer and Fluid Laboratory to achieve a uniform distribution of surface temperatures of batteries in electric vehicles. The concept’s functionality has been already confirmed in the numerical simulation by finding the spatial distribution of the thermal resistance that needs to be applied on the battery surface to obtain the uniform temperature distribution. The main objectives are: (i) to check suitability of a cutting plotter and find its limits for production of the compensation foil, (ii) to design and test the technology of application of the foil on the battery, including the materials needed to fill the holes made after using the plotter and generate the necessary and wide range of the effective thermal conductivity, (iii) to measure the surface temperature of the battery with and without the foil. The battery may be replaced by the dummy cell with an electric heater.

2. Lattice-Boltzmann method in transport calculations inside porous media

   Porous media can be encountered in fundamental phenomena of physics as well as in various applications of industry. In Heat Transfer and Fluid Flow Laboratory one can come across two following examples. In metallurgical and steel processes the formation of oxide scales takes place on hot surfaces of materials being processed. Oxide scales are thin layers of iron oxide with thickness ranging between a few and hundreds of micrometers. Oxide scales often contains many pores having various orientation. Presence of such pores naturally affects the thermo-physical properties. In composition different iron oxides have a different impact on the cooling intensity of hot surfaces. In many topic-related processes is knowing the exact cooling intensity essential. Use of polymeric hollow fibers in heat exchangers could be listed as a second example of a porous structure. Often having a diameter of less than one millimeter, fibers are relatively long and several thousands of them can be utilized in one heat exchanger. The performance of the heat exchanger as well as the pressure drop are strongly dependent on orientation of fibers. Therefore, an optimal pattern of fiber distribution should be searched for. Numerical methods are frequently being engaged to explain some fundamental physical phenomena or to optimize engineering processes. The most of commonly used commercial software is based on finite element and finite volume codes that are inherently problematic when it comes to generation of geometry and computational grid. Lattice-Boltzmann method appears to be a suitable alternative. In fact, it has been already proved to perform very well in simulations of transport mechanisms inside porous media. For example, the open-source software PALABOS allows working directly with raw data obtained by a tomography imaging, which are typically represented by a voxel matrix. The main goal of this work is a simulation of fluid flow and heat transfer in porous structures, which geometry can be delivered by a tomography imaging. It is assumed that the calculations will be performed in parallel on one of the Czech supercomputers. Given a large data being processed, it is further anticipated that the I/O operations will be also done in parallel. A possibility of local lattice refinement will be considered for setups with only a partial occupation of a porous structure. In addition, a physically correct, yet a highly parallel, algorithm will be introduced for setups with multi-material zones coupled via appropriate conjugate boundary conditions.

3. Optimization of the water nozzle for cooling cylindrical surfaces

   Several years of studies have shown that there are no water nozzles on the market that are optimized for cooling cylindrical surfaces. The goal of the work is to optimize the internal geometry of the water nozzle in order to achieve an effective distribution of water on the cylindrical surface, and thus the most efficient cooling. The optimization will require simulation of single-phase flow inside the nozzle and two-phase flow when the liquid flows in free space (in air). Prototypes will be made for the designed nozzles, which will then be verified using laboratory experiments. The distribution of impact pressure from water falling on a flat surface will be measured using the experimental equipment that the laboratory is equipped with, and thus the correctness of the calculation model will be verified. The effectiveness of the cooling of the cylindrical surface will be verified on an experimental device that the laboratory is also equipped with. During optimization, the use of an industrial tomograph to study the internal structure of the water jet is also assumed.

4. Structural integrity of additively manufactured polymer materials

   While additive manufacturing of polymers, has become increasingly popular for design studies, rapid prototyping and the production of noncritical spare parts, its application in structurally loaded components is still scarce. One of the reasons for this might be skepticism of engineers due to the lack of knowledge regarding the expected lifetime and reliability as well as knowledge to failure mechanisms. Therefore presented work will be focused on fatigue damage of additively manufactured polymer materials, experimental testing of such materials as well as on numerical modeling of fatigue damage and fatigue crack propagation. This work will be solved in close cooperation with PCCL- Polymer Competence Center in Leoben.
