Aim
The aim of the course is to acquaint students with the design and operation of steam and gas turbine equipment used in the energy industry. The specifics of the turbines used in different fields and the limitations of their applicability are presented. Through the energy conversion processes of turbines, students learn the interplay of different components, the possible parameter ranges of power and efficiency. The student is introduced to the characteristics of industrial and aeroderative gas turbines, their main characteristic parameters, construction designs.
Learning outcomes
Competences that can be acquired by completing the course
Knowledge
Student has a comprehensive knowledge of the applications of steam and gas turbines. Student has an accurate knowledge of the state changes that take place in the stages of turbines. Student is aware of ways to control turbines. Student informed about the current development directions of the turbines. Informed about the equipment for each power control mode. Student know how to edit and define the profiles that make up the blades. Student is aware of the events that occur in the turbine nozzle in case of flow above the speed of sound. Knows paddle twist and paddle strength sizing. Student is aware of the operating parameters of nuclear power plant steam turbines. It names the relationship between blade erosion and specific moisture content. Student is aware of the application of Stodola's steam cone law and its cryolts. Describes the parameters that characterize the workflows of gas turbines. Student knows the main parameters of compressor operation and the limitations of its applicability.
Ability
Selects the turbine equipment that best suits the appropriate initial parameters. Defines the main dimensions of the turbine stage with specific status indicators. It distinguishes between quantitative and qualitative regulation. Proposes a turbine design to suit individual needs. Distinguishes between power control modes. Selects the main features of the blade profile to suit your needs. Apply the radius deflection calculation in a given nozzle channel. Determines the cross section of the turbine blade as a function of radius. It distinguishes between wet and superheated steam initial parameter turbines. Analyzes possible moisture reduction procedures. Solves the calculation of the parameter change that occurs during turbine control. Analyzes the effect of parameter changes in gas turbines on performance and efficiency. Evaluates the operation of axial and centrifugal compressors.
Attitude
Student constantly monitors his work, results and conclusions. It continuously expands its knowledge related to the design and operation of steam and gas turbines. Open to the use of information technology tools. It seeks to routinely use equations that describe state changes in stages. It develops your ability to provide accurate and error-free problem solving, engineering precision and accuracy. He publishes his results in accordance with his professional rules. It monitors the development of energy production equipment. It publishes its opinions and views without offending others.
Independence and responsibility
Collaborates with the instructor and fellow students to expand knowledge. Accepts well-founded professional and other critical remarks. In some situations, as part of a team, you work with your fellow students to solve tasks. With his knowledge, he makes a responsible, well-founded decision based on his analyzes. Student is committed to the principles and methods of systematic thinking and problem solving.
Teaching methodology
During the teaching of the subject, the lecture and practice are separated from each other, both in terms of content and methodology. The lectures basically introduce students to the information defined by the knowledge competence elements using the technique of frontal education. The lectures deal with the description of a theoretical question and its application in practice. Many of the descriptions of parts and equipment presented at the presentation help to develop system-level thinking. During the exercises, the knowledge previously acquired at home, independently, is solved partly jointly and partly individually with the help of the practice leader. An individually published homework contributes to an independent immersion in the topic.

General rules
Learning outcomes are assessed on the basis of two mid-year written performance measurements (two summative assessment of academic performance). Summarizing academic performance evaluation: a complex, written way of evaluating the competence-type competence elements of the subject and knowledge in the form of an indoor dissertation, the dissertation focuses on the application of the acquired knowledge, so it focuses on problem recognition and solution, on the other hand, asks for the necessary lexical knowledge during the performance appraisal, the working time available is 60 minutes; Partial performance assessment (homework): a complex way of evaluating the knowledge, ability, attitude, as well as independence and responsibility type competence elements of the subject, the form of which is the individual homework.
Assessment methods
Detailed description of mid-term assessments
| Mid-term assessment No. 1 | ||
| Type: | summative assessment | |
| Number: | 2 | |
| Purpose, description: | Summative assessments collectively examine and assess students ’learning outcomes defined by knowledge and ability type competencies. Accordingly, each summative assessment assesses the acquisition of the designated theoretical knowledge as well as the existence of the knowledge and skills acquired in practice. Each summative assessment focuses 65% on theoretical knowledge and 35% on application skills. They will be completed on the date specified in the academic performance assessment plan, expected to be in the 8th and 14th weeks of education. Each of the two summary performance evaluations can earn 40-40 points. | |
| Mid-term assessment No. 2 | ||
| Type: | formative assessment, project-based, complex | |
| Number: | 1 | |
| Purpose, description: | The basic goal of partial performance assessment is to examine the existence of attitudes and learning outcomes belonging to the autonomy and responsibility competence group. The way to do this is to create a self-developed complex homework. The tasks are different for each individual, but have the same difficulty. The content and formal requirements and evaluation principles of the completed homework are included in the terms of reference. You can get up to 20 points with this task. The task is issued and controlled by a practice leader. | |
Detailed description of assessments performed during the examination period
The subject does not include assessment during the examination period.
The weight of mid-term assessments in signing or in final grading
| ID | Proportion |
|---|---|
| Mid-term assessment No. 1 | 80 % |
| Mid-term assessment No. 2 | 20 % |
The weight of partial exams in grade
There is no exam belongs to the subject.
Determination of the grade
| Grade | ECTS | The grade expressed in percents |
|---|---|---|
| very good (5) | Excellent [A] | above 90 % |
| very good (5) | Very Good [B] | 85 % - 90 % |
| good (4) | Good [C] | 72 % - 85 % |
| satisfactory (3) | Satisfactory [D] | 65 % - 72 % |
| sufficient (2) | Pass [E] | 50 % - 65 % |
| insufficient (1) | Fail [F] | below 50 % |
The lower limit specified for each grade already belongs to that grade.
Attendance and participation requirements
The lack of the value means that there is no attendance requirement.
At least 70% the exercises (rounded down) must be actively attended.
Special rules for improving, retaken and replacement
The special rules for improving, retaken and replacement shall be interpreted and applied in conjunction with the general rules of the CoS (TVSZ).
| Need mid-term assessment to invidually complete? | ||
| yes | ||
| Can the submitted and accepted partial performance assessments be resubmitted until the end of the replacement period in order to achieve better results? | ||
| NO | ||
| The way of retaking or improving a summary assessment for the first time: | ||
| each summative assessment can be retaken or improved | ||
| Is the retaking-improving of a summary assessment allowed, and if so, than which form: | ||
| one single, combined retake or grade-improving exam is possible for all assesments | ||
| Taking into account the previous result in case of improvement, retaken-improvement: | ||
| new result overrides previous result | ||
| The way of retaking or improving a partial assessment for the first time: | ||
| partial assesment(s) in this group can be improved or repeated once up to the end of the repeat period | ||
