Turbines and Turbocompressors (FSI-LT1)

Academic year 2023/2024
Supervisor: doc. Ing. Jan Fiedler, Dr.  
Supervising institute: EÚ all courses guaranted by this institute
Teaching language: Czech
Aims of the course unit:

The target of the course is to enable students to understand the basic principles of turbines and turbocompressors so that they are able to work at any level of design, production and operation of turbines and turbocompressors.
Learning outcomes and competences:

The result of the course is the education of students in the field of fluid dynamics, wind turbines, heat turbines and turbocompressors.
Prerequisites:

Theory of turbomachines, thermomechanics basics and the basics of energy industry.
Course contents:

The course Turbines and turbocompressors is a direct continuation of the course Turbomachines (LLS). The introductory part of the course is devoted to fluid dynamics, which complements the theory of turbomachines so that it is possible to explain the design and operation of wind and heat turbines and turbocompressors in a comprehensive and contextual manner. Construction, design, operational, economic and ecological impacts are continuously pointed out. During the course of study, students are introduced to the development of knowledge bases and their application in the design of heat turbines and turbocompressors, achieved results and future prospects.
Teaching methods and criteria:
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: Credit: Active participation in the exercise. The ability to solve assigned problems is verified. Solving the credit problem is a condition for obtaining course-unit credit.

Exam: The knowledge acquired during the entire semester is tested.
The exam has a written part and a conditional oral part.
The final evaluation is composed of the results of the credit and the exam.

 
Controlled participation in lessons:

Semestral exam.
