Base Knowledge
None.
Teaching Methodologies
Theoretical lectures with presentation and explanation of the essential part of the subject matters. Students will be encouraged to a deep understand of these issues, using the recommended literature and possibly other books or documents.
Theoretical-practical lectures to solve different problems with discussion of the applications studied. In some theoreticalpractical classes are made visits to the laboratories for students to take contact with the most common thermodynamic systems.
In both type of lectures, students are asked about the possible applications of the principles and laws of thermodynamics.
Students may obtain approval in a final exam of the discipline. In each part of the examination (theoretical and theoreticalpractical), it must be obtain an approved percentage of at least 30%.
Learning Results
The main objective is to give students the basic scientific training in the Thermal Engineering area, preparing them not only to solve some problems related to thermal systems but also to easily integrate the study of subsequent and related matters.
The knowledge gained in this course will contribute significantly to students to acquire the following specific responsibilities:
– Understand and know how to apply the laws of Thermodynamics and Heat Transfer, including the ability to conduct heat balances;
– Ability to size, install, operate and maintain HVAC and refrigeration systems;
– Understanding the operation and be able to install, operate and maintain thermal machines in general and in particular internal combustion engines.
