EXPECTED LEARNING OUTCOMES
The course provides the student with knowledge of the understanding of physical principles and the phenomena of fluid mechanics. In particular, after the successful completion of the course, the student /tria will be able to:
• Have a supervision of the phenomena that the mechanics of fluids heal
• Understand the low-key view of Navier Stokes equations and be able to associate mathematical and engineering concepts for the modeling of physical problems of fluid engineering.
• Give a mathematical description of the movement of real fluids for basic flows based on Navier-Stokes equations by applying appropriate simplifications for engineering problems.
• To deal with fluid engineering problems in cases of static, and in cases of movements in a small and large number of Reynolds.
• To be able to simplify theoretical knowledge and apply it to basic fluid engineering problems in the laboratory.
• Be able to interpret phenomena and measure specific physical amounts in flows that occur in mechanical engineering problems through laboratory exercises.
Search, analysis and synthesis of data and information, using the necessary technologies with the combination of laboratory exercises and theoretical knowledge.
