Fluid Dynamics Andrea Crivellini
Fundamentals of mathematical analysis and physics
KNOWLEDGE AND UNDERSTANDING:
This course aims at giving students the basic knowledge of fluid mechanics. Together with the fundamentals in mathematics and physics, this course will increase the knowledge in the field of industrial engineering with particular focus on thermofluid-dynamics giving the student the awareness of the multidisciplinary context of engineering with particular focus on the issues related to the conversion, transmission, final use of energy and to the design of fluid machines and energy systems.CAPACITY TO APPLY KNOWLEDGE AND UNDERSTANDING:
Aiming at applying the fundamentals of fluid mechanics in the industrial sector, students must be able to face engineering problems by means of suitable and well-timed methodologies and techniques. The main skills acquired in the course are: 1.basic knowledge of the fluid dynamics governing equation; 2. ability to evaluate for simple systems the fluid dynamics loads; 3. Ability to perform fluid dynamics analyses on simple steady state systems using the control volume techniqueTRANSVERSAL SKILLS:
The ability of solving numerical problems, together with the awareness of their knowledge, will improve the judgement autonomy of students, their communications skills and their learning ability
Introduction: The field of fluid mechanics; approximation of continuous; stress on a point; definition of fluid; properties of fluids.
Conservation of mass and momentum

Development of the examination
LEARNING EVALUATION METHODS
The assessment of the students preparation will be performed via a written and oral examination. In the written test, the student will be asked to demonstrate the knowledge of the general criteria for the calculation of forces exchanged between a fluid, which can be in motion or at rest, and a body, using different methodologies and mathematical models explained during the course. In the oral test, the student is asked to deduce the most important physical laws governing the fluid motion, the assumptions involved and the resultant applicability limits.
LEARNING EVALUATION CRITERIA
Within the examination, the student must demonstrate the knowledge of the principal physical laws governing the fluid motion, knowing how these laws can be prooven, and the ability to use the methodologies and the mathematical models presented during the course. In addition, the student must show a sufficient ability in the synthesis and in the link between all the different topics dealt within the course.
LEARNING MEASUREMENT CRITERIA
Grading scheme is based on a scale of 30 points. Successful completion of the examination will lead to grades ranging from 18 to 30.
FINAL MARK ALLOCATION CRITERIA
The maximum mark, which is thirty with laude, is awarded to students that demonstrate in the tests a complete autonomy in formulating and solving the problems, with an outstanding ability to use the methodologies and mathematical models proper of the fluid dynamics. The minimum mark, which is eighteen, is awarded to students that demonstrate the ability to solve the tests with sufficient knowledge of the methodologies and mathematical models proper of the fluid dynamics. The admission to the oral examination is subordinate to passing the written examination. The final grade is due to the result of the oral examination. This grade will be the sum of the grades obtained in answering two questions.
