Course detail

Turbines and Turbocompressors

FSI-LT1Acad. year: 2023/2024

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.
