Teaching method

Lectures combine the presentation of the theoretical concepts with the use of slide projection containing schematic illustrations with important aspects related to the subject and the resolution of exercises by the students. Group resolution is encouraged. At the end of each class the problem is solved.

Evaluation method

The continuous evaluation of the subject consists of two components:
1. Three individual tests. Each test is assessed by 0 to 20 points.
-1st Test: Momentum transport through molecular mechanism, has a weight of 15% in the final mark.
2nd Test: Momentum transport through turbulent mechanisms: 35% of the final mark. The minimum grade for this test is 9/20.
3rd Test: Heat transport: weight for final mark 35%.
2. Realization of a group work. Group work (maximum of 4 students) on an exercise involving transport of momentum and heat transport.
Final mark = 0.15 × 1st Test mark + 0.35 × 2nd Test mark + 0.35 × 3rd Test mark and + 0.15 × group assignment mark
The marks of the tests and the work are rounded to one decimal place. The final mark, rounded to the nearest whole number, must be greater than or equal to 10 points in order to pass the course.
If the student does not pass the continuous assessment or chooses not to take the continuous assessment, he/she will have the right to take the exam. A minimum classification of 10 (9.5) on a scale of 0 to 20 is required.)
