Title of the subject: Turbines, Turboblowers, Fans

Semester_of_study (WT – winter/ST – summer): WT

Learning outcomes: The student will become familiar with basic principles of steam, gas and water turbines. He/she will be familiar with the thermodynamic foundations of thermal cycles in heat turbines and hydromechanics in water turbines. He/she will be introduced to the characteristics of individual types of turbines and also the calculation of basic thermal, hydraulic and structural parameters. He/she will be familiar with individual types of fans, fan drives, operating conditions, installation, operation, maintenance and economy of operation. At the end of the course the student will be able to analyze the suitability of the construction of the machines for selected parameters (location, flow ...) and determine the operating characteristics and control of the analyzed machines. He/she will learn to determine the proper operation of machines and their maintenance.
