ECTS Credits: 5.0

Aims

• Physical phenomenon and associated hydrodynamic theory relating to advanced hull and propeller flow and hence resulting ship resistance and propulsion;
• Methods which are mainly computational and based on potential flow theory, to model the above mentioned hydrodynamic properties (in A1) of a ship hull and its propulsor;
• Hydrodynamic design of a conventional ship hullform with specific emphasis on its forebody and afterbody sections;
• Hydrodynamic design of a conventional propeller and its performance analysis;
• Basic principles, design and performance characteristics of unconventional propulsors.

Outline Of Syllabus

Nature of hull forms: Nature of ship flow (Resistance & Wake); basic theory for computational flow & resistance; Computational methods for prediction of flow around the hull and that of ship resistance; (CDF - software demonstration, if possible); Hydrodynamic bulbous bow and design; Hydrodynamic aft-body design. Fundamental theories of propeller action (Momentum theory; blade element theory; Vortex theory); propeller design and analysis methods (lifting line design; blade section design; lifting surface analysis); Unconvential propulsors (an overview of principles, design and performance of some popular types of unconventional propulsors, e.g. Ducted propellers; freely rotating/fixed guide vanes; azimuthing podded propulsors etc).

Teaching Rationale And Relationship

Lectures in the classroom provide the student with general understanding of and familiarity with the fundamentals of advanced ship (hull) and propulsor flows and associated computational tools (IKO1-6); To estimate resistance and propulsor performance during these tools; to estimate resistance and propulsor performance using these tools; to be able to perform hydrodynamic design of the critical parts of the hull and its propeller (ISO1-3). Resistance and propulsion aspects of all ship types are broad, diverse and dynamic while this specific course has relatively limited lecture hours. The students are therefore strongly recommended and guided to read classic books and the state of the art papers to cover a wide range of vehicles/propulsors and catch-up with the latest developments in this important subject area (IKO1-6).

Assessment Rationale And Relationship

The formal examination provides the opportunity for students to demonstrate both their knowledge and skills across a range of the course topics under time limited conditions, this being of value in any subsequent employment.

The Graduate Skills Framework indicated as ‘A’ are also assessed in this way.
