Learning outcomes of the course unit
The course enables graduates to process project documentation in power engineering including optimization thermal calculations.
Prerequisites
Knowledge of Boilers and Heat Exchangers, Energy Sources and Transformation and Thermal Turbines I
Planned learning activities and teaching methods
The course is taught in the form of lectures that have the character of explaining basic principles and theory of the mentioned discipline.
The calculation classes will be based around Open Source software OpenModelica. During the semester, video-lectures will be regularly released on University Moodle website. The videos will contain theory to each section and their implementation into the program. There will be individual assignments corresponding to covered topics. At the given scheduled time for the class there will be computer lab available, where individual consultations can take place.
Assesment methods and criteria linked to learning outcomes
Credit requirements: active participation in seminars, submission of given project according to the set deadline.
Exam requirements: written part in the form of questions and numerical problems, oral part in the form of discussion on given topic.
Aims
