OVERVIEW

The course of HYDRODYNAMICS  provides the first basic knowledges on Fluid Mechanics to the students of the study course of Ingegneria Nautica. This course spans approximately 60 hours over one semester and provides 6 credits.

AIMS AND CONTENT

LEARNING OUTCOMES

The course aims to provide students the foundation for the study of fluid dynamics, that is, the tools for the description of the motion of fluids and for the prediction of their movement knowing the forces exerted on them .

AIMS AND LEARNING OUTCOMES

Evaluation of static forces on immersed plane and curved surfaces. Design and analysis of simple pipe networks, fluid machineries.

TEACHING METHODS

The lectures are organized in about 12 lessons. Eachone characterised by a first theoretical part and a second part of practice, with example problems.

SYLLABUS/CONTENT

Fundamentals - Fluid properties and classification. Cinematics of fluids. Eulerian and Lagrangian description of motion. Cauchy's continuum, forces, pressure and stresses. Stress in a fluid at rest. Hydrostatic law. Stress in a fluid in motion. Material and local derivatives. Conservation of mass and momentum principle in integral and local form. Inviscid fluid and the Bernoulli's law.

Fluid at rest: hydrostatics - Pressure distribution in an uncompressible fluid and in a compressible, barotropic fluid. Forces on immersed plane and curved surfaces. Buoyancy. Stability of floating and immersed bodies.

Fluid in motion: one-dimensional flow - Definition of cross-averaged quantities. Conservation of mass and momentum principle
for a one dimensional flow: continuity and momentum equations.

Flow in pipes - Uniform and steady flow in a pipe. Friction losses. Local dissipations of energy. Design and analysis of simple
pipe networks, fluid machineries.

EXAMS

EXAM DESCRIPTION

Examination consists of a written test and an oral interview on the entire course program. Three appeals take place in the summer session (June, July and September) and two appeals in the winter one (January and February). The written part consists in the solution of 4 exercises on:

1. forces on submerged plane surfaces
2. forces on submerged curved surfaces
3. the conservation of mass and momentum principles
4. the design of simple piping systems

Candidates must be provided with pen, pencil, rubber and calculator. Books or texts and mobile phones are not allowed.

In order to access to the interview, the student is required to pass (score larger than 18) the written examination. The oral interview must take place on the same date of the written test and consists of questions on the written test and on the program in general.

Alternatively, there will be two midterm exams (the first generally in November and the second at the end of December) that will grant, if passed (average score larger than 18), direct admission to a brief oral interview (to be held in January). Only the students achieving a score larger than 15 in the first midterm examination are allowed to access to the second midterm examination.

ASSESSMENT METHODS

The written test typically aims to ascertain the ability to apply the principles of fluid mechanics and to solve complex engineering problems that can be tackled in few hours, with the use of simple means of calculation (calculator with the four operations and simple mathematical functions). The interview completes the written part, dealing with the subjects whose learning cannot be directly ascertained with the written test. In the interview, questions that require the solution of simple problems on the blackboard are asked to the candidate. The interview also allows for a verification of the student's communication skills.
