Teaching Methodologies and Assessment Criteria |
Teaching methodologies are based on mixed theoretical/practical and practical approaches. There are 2 classes per week with 2 hours each. In one the theoretical concepts are given, followed immediately by practical illustrations. In the practical class, numerical exercises involving application of the theory to concrete thermodynamics engineering problems are solved. In addition, there are two laboratory classes.
The evaluation is based on a written test (75%), a lab work (17,5%) and active participation in the practical classes (7,5%) and/or an exam (82,5%) and lab (17,5%). Marks above 16 require a final oral examination. Min mark in written test/exam 8,5 (/20). Test: 10 Jan 2024 11h-13h
