Course content
|
The course addresses the issues of steam and gas turbines, covering key areas such as the fundamental theory of fluid flow and thermodynamics in turbomachines, as well as the description of design solutions for steam and gas turbines, including axial and radial compressors of turbo-compressor engines. The practical sessions involve solving real-world examples, such as analyzing the thermodynamic cycle of a gas turbine, calculating the basic parameters of a radial/axial compressor in a turbo-compressor, or performing a simplified design of a single-stage gas turbine. These sessions are complemented by laboratory tasks conducted on the ET-792 gas turbine training model and the VT-400 air turbine. During the semester, the following topics will be gradually covered in lectures and practical sessions: 1. Thermodynamic principles of steam and gas turbines (analysis of thermodynamic cycles - Rankine vs. Brayton, concepts of exergy and entropy, comparison of ideal and real cycles). 2. Flow analysis in turbine passages (Euler's turbine equation, examination of two-dimensional and three-dimensional flows, aerodynamics of blade cascades) 3. Losses in turbine flow path (classification and sources of losses, overview of selected loss models, efficiency and loss coefficients) 4. Simplified turbine stage design ("Meanline" design of the turbine flow path, strategies for blade profile design, velocity triangles, theory of radial equilibrium) 5. Turbo-compressors (design of radial and axial compressors, compressor performance characteristics, instabilities in compressors and methods for their mitigation) 6. Combustion chambers of turbo-compressor engines (combustion processes, design solutions for combustion chambers, combustion methods and their environmental impact) 7. Cooling of thermally stressed parts of gas turbines (cooling methods, materials used for high-temperature applications)
