Thermal Turbines I
FSI-LT1Acad. year: 2019/2020
The course "Thermal Turbines I" extends the knowledge of fundamental physical processes in the transformation of thermal or pressure energy into the power, and vice versa in the transformation of the power into thermal or pressure energy, acquired in the previous course of Turbo-machines. The lectures are concerned with principles and properties of direct and indirect thermal cycles in working fluids with and without changing their phase. A sufficient range of lectures is devoted to the study of processes and design possibilities to reach the highest possible efficiency and reliability of steam turbines, gas turbines and turbo-compressors. Also dealt with are the design, operational, economic and environmental impacts. The students will learn the basics and their application in the design of thermal turbines and turbo-compressors. They will be made familiar with the currently results and with future prospects.
Learning outcomes of the course unit
Students will understand theories and their usage in design and construction of thermal turbines and turbochargers, they will learn how to perform calculations and design thermal schemes of thermal turbines, thermo-dynamical and solidity calculations and construction of thermal turbines stages as well as multistage steam and gas turbines and turbochargers.
Thermo-mechanics basics and the basics of energy industry.

Planned learning activities and teaching methods
The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.
Assesment methods and criteria linked to learning outcomes
Course-unit credit requirements: Active participation at seminars. Systematic control of continuous study and effort regarding the application of the knowledge acquired at lectures to simple tasks in the area of the design of functional parts of blade machines. Examination is written and oral. The knowledge of used physical laws and their application to specific types of blade machines is tested as well as construction variants of basic functional parts and connections of constructional variant and applied attributes of these machines. Relation of working conditions of blade machines and their constructional variants.
Language of instruction
The course objective is to make students familiar with basic principles and details of phenomena related to transformation of thermal or pressure energy to the mechanical one and vice versa, finding constructional and other solutions for the usage of desirable phenomena and elimination of the non-desirable ones.
Specification of controlled education, way of implementation and compensation for absences
Attendance at seminars is required. Compensation of missed lessons to be negotiated with a teacher.
