## ADVANCED FLUID MECHANICS

CODE 97233 2021/2022 5 cfu during the 1st year of 10720 ENVIRONMENTAL ENGINEERING (LM-35) - GENOVA ICAR/01 GENOVA 1° Semester This unit is a module of: AULAWEB

## OVERVIEW

The course introduces the student to the study of fluid mechanics showing the equations
that control the motion of a fluid and obtaining some particular solutions of the hydrodynamic problem in order to provide the essential skills that are necessary to face practical problems

## AIMS AND CONTENT

### LEARNING OUTCOMES

Presents the fundamental principles and laws that govern the motion of fluids. Simple practical problems are formulated and solved and the foundation to tackle more complex problems are laid

### AIMS AND LEARNING OUTCOMES

the frequency and the active participation in the training activities (lectures and exercises) will allow the student 1) to formulate the problem of fluid motion in the correct way, 2) to identify the most appropriate approach to obtain the solution, according to the values
of the parameters that control the flow of fluids, 3) to evaluate the forces that the fluids exert on moving bodies or, in a similar way, to determine the forces exerted by a fluid that flows around a structure. At the end of the course, the student will be able to describe the motion of a fluid both in the laminar regime (for example the motion inside the circulatory system) and in the turbulent regime (for example the motion along a river or the motion generated by the wind that flows around a building) and to evaluate the forces exerted
from a wave against a breakwater or to estimate the lift that keeps an airplane in flight.

### PREREQUISITES

To follow the course successfully, it is necessary to know the basic principles of physics and thermodynamics, which however will be briefly recalled during the course. Furthermore, the knowledge provided by the courses of analysis and mathematical physics is essential

### TEACHING METHODS

The course consists of lectures for a total of about 50 hours
and exercises for a total of about 10 hours. The attendance at lessons and exercises is strongly recommended.

## EXAMS

### EXAM DESCRIPTION

The exam consists of an oral examination during which the student will have to show that she/he has learned the topics explained during the course and the capability to formulate correctly a hydrodynamic problem as well as to choose the most appropriate approach to determine the relative solution

### ASSESSMENT METHODS

The exam aims at ascertaining the following aspects of student's preparation:
1) knowledge acquired about the basic concepts of the course, 2) capability to apply the knowledge acquired within specific contexts. The possession of these components
of the student's preparation will be ascertained through specific questions.
