    Learning Activities and Methodology:

    Lectures: the main concepts of fluid mechanics are derived rigorously using physical and mathematical tools.
    Seminars: the concepts derived in the lectures are used to solve problems. Also, new concepts are introduced through examples.
    Homework: two homework covering different areas of Fluid Mechanics are given to the students.
    Lab sessions: the students will become familiar with the usage of numerical (computational) and experimental tools to investigate a canonical flow of biomedical interest.

    Assessment System:

    1) Mid-term exam. It will cover approximately half the programme. If the grade is >= 5.0, the students do not need to take the exam on this part in the final (40% of the total grade)
    2) Final exam. It will cover the second half of the programme. Additionally, the students will have another opportunity to pass the exam of the first half. A minimum grade of 5.0 in the final is required to pass the course (40% of the total grade)
    3) Homework (10%). There are two homework that the students are expected to complete.
    4) LAB SESSION (4): Semi-analytical/Numerical simulation of the flow in an artery. Experimental characterization of the flow using Particle Image Velocimetry (PIV). The lab report will be 10% of the final grade.
