Experimental and numerical methods for ship resistance and propulsion

• describe the assumptions associated with theoretical models and calculation methods associated with the resistance and propulsion of ships
• explain the theory behind model testing for resistance and propulsion (Froude scaling)
• organize and execute a series of ship model tests
• perform calculations that transform data from model to full scale by ITTC-1978 or a similar procedure
• calculate and assess the flow, including the generated wave system, around the ship with commercial software
• describe the function of ship propellers, and explain the use of propeller diagrams (for instance the B-series propellers)
• apply propeller diagrams to identify an optimum propeller
• explain the interaction between ship, propeller, and main engine
• specify the propulsive main engine that performs best with the ship and its propeller
• collect experimental and numerical results in a high-quality technical report

Experimental and computational methods to predict resistance and propulsion in calm water. Froude scaling. Resistance model tests (ITTC-1978) with optimization of a bulbous bow. Power prognosis on the basis of the model tests, and calculation of the optimum combination of main engine and propeller (B-series). It is emphasised that the students must take an active part in the planning, preparation, testing, and analysis of the model tests.
