Course detail
Turbines and Turbocompressors
FSI-LT1 Acad. year: 2023/2024 Summer semester
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.

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.
Semestral exam.
Aims
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.
The result of the course is the education of students in the field of fluid dynamics, wind turbines, heat turbines and turbocompressors.
