B6362 - Hydrodynamics

Learning outcomes

The main objective of the course is to provide the student with the theoretical physical-mathematical bases and the tools necessary for the evaluation and analysis of the dynamics of vessels advancing at sea. At the end of the course the student will be able to understand and apply different theories that concern both specific aspects (e.g. waves, sea environment, hull) and the overall response of vessels to any sea condition.

Course contents

1. WINDSHIPS AND SAILING YACHTS (nomenclature, sail aerodynamics, free-body diagram including static and dynamic forces).

2. FOILING VESSELS (hydrodynamics of foils, free-body diagram including static and dynamic forces, stability and control).

3. SEAKEEPING (ship's and yacht's motions and responses, motions in regular and irregular waves, limiting factors, wave data and RAO, stabilization).

4. MANOEUVRING (directional stability and control, classical manoeuvres and evaluation of manoeuvring ability, manoeuvring devices, rudder area forces and torques, vessel handling, dynamical stability).

5. VELOCITY PREDICTION PROGRAMMES (methodologies to predict vessel's performances in static and dynamic conditions including wind and wind-assisted propulsions for displacement, planning, and foiling hulls).

Lecture Notes provided by the Lecturer

Teaching methods

Lectures and frontal exercises held by the teacher. During the course, seminars could be organized held by highly qualified personnel and regarding technological aspects of the course. The topics of the seminars held will form an integral part of the program and may be subject to verification during the exam.

Assessment methods

The assessment will take place through an oral examination in which the student must demonstrate sufficient skills of the topics presented in class and be able to summarize the knowledge gained. The student must demonstrate sufficient preparation in each of the required topics. The final grade will be assigned by the committee based on the overall preparation demonstrated.

Teaching tools

Whiteboard /blackboard and PowerPoint presentations.
