Course detail

Theory of Energy Transformation, Power Units

FSI-QTS Acad. year: 2024/2025 Winter semester

The course introduces students to the theory of propulsion units with a focus on thermodynamics of working cycles, combustion and heat transfer. The theory of energy transformation is included. The course covers all types of propulsion i.e., the use of hydrocarbon floats, alternative boats, hydrogen, sysnthetic fuels, and electricity.

Learning outcomes of the course unit

Prerequisites

Prerequisites and co-requisites The student must have knowledge corresponding to subjects of theoretical basis of bachelor study in the field of engineering education, especially thermodynamics and Heat Transfer.

Planned learning activities and teaching methods

Assesment methods and criteria linked to learning outcomes

The credit is conditional on active participation in the exercises, proper preparation of the elaborations and fulfilling the conditions of any control test. The examination verifies the knowledge acquired in lectures and exercises, is written, including a test in e-learning, and may have an oral part verifying knowledge after the written part.

Classes are compulsory, attendance is checked by the teacher. The form of substitution of lessons missed for serious reasons and in exceptional cases is solved individually with the course supervisor.
