OVERVIEW

The course of HYDRODYNAMICS provides the first basic knowledge on Fluid Mechanics and Hydraulics 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

Operative skills: Evaluation of hydrostatic forces on immersed plane and curved surfaces. Design and analysis of simple pipelines, also with the aid of fluid machineries.

PREREQUISITES

"Analisi Matematica" and "Geometria"

TEACHING METHODS

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

Frontal classes are in presence. For logistic reasons, the lessons could be extraordinary given completely or partly (mixed teaching) online in direct streaming in an extension not exceeding the 10% of the planned hours.

SYLLABUS/CONTENT

Fundamentals of fluid mechanics - Fluid properties and classification. The continuum hypothesis. Cinematics of fluids. Eulerian and Lagrangian description of motion. Volume and surface forces acting on a fluid, pressure and stresses. Stress tensor in a fluid at rest. Hydrostatic law. Stress tensor in a fluid in motion. Material and local derivatives. Conservation of mass and momentum principles in integral and local forms. Inviscid fluid and Bernoulli's theorem.

Dimensional analysis - The π theorem. Similitude and modelling.

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

Fluid in motion - Fluid current: definition of cross-averaged quantities. Conservation of mass and momentum principles for a current.
Pipe flow: evaluation of friction losses and local dissipations of energy in a steady and uniform flow. Design and analysis of simple pipe systems. Hints on pumps and  turbines.

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 session (January and February). The written part consists of the solution of 4-5 exercises focusing on:

  1. forces on submerged plane surfaces
  2. forces on submerged curved surfaces
  3. the conservation of mass and momentum principles
  4. applications of Bernoulli's theorem for fluid currents
  5. the design of simple pipe 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 consists of questions on the written test and on the program in general.

Alternatively, there will be two midterm exams (the first one generally in November and the second one 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 exclusively 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 engineering problems that can be tackled in few hours, with the aid of simple means of calculation (calculator with the four operations and simple mathematical functions).
The test comprises a hydrostatic problem and a problem consisting of the design of a pipeline.

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 student's expository and communication skills.
