Marine Hydrodynamics

- Fundamental fluid mechanics
- Viscous fluids (Euler and Navier-Stokes equations, Boundary layers and separation, laminar vs. turbulent flow)
- Ideal fluids (Potential theory, Laplace equation)
- Description of ocean environment (Wind, Current, waves and wave theories, Regular waves, Irregular waves)
- Hydrodynamic forces (Large-volume structures, Small-volume structures (Morison equation), Wave forces)
- Applied ship hydrodynamics:
- Resistance (on stream lined bodies, lift and drag, hull resistance)
- Propulsion (Propulsion systems, efficiencies)
- Ship motion (General dynamics, transfer function, natural frequency, damping)
- Model testing (Towing test, propulsion test, open water test)

Knowledge:
- shall have a fundamental understanding of the mathematical models used in general fluid mechanics.
- shall be familiar with linear wave theory and understand how irregular ocean waves can be established from the fundamental regular components.
- shall be familiar with how the ship resistance can be split into separate components and understand how the various components can be established by model tests and various calculation methods.
- is aware of the fundamentals of propeller theory and knows how the propeller characteristics can be established by model tests and various calculation methods.

Skills:
- knows how to apply fundamental mechanical principles to predict hydrodynamic forces.
- knows how to calculate wave forces on slender marine structures.
- knows how to use the results from model tests to establish the total resistance of a ship.
- knows how to combine results from model tests and various calculation methods to establish an estimate of the required installed power in a ship.

General competence:
-is aware of the complex interaction between a ships resistance and the propeller characteristics.
-is familiar with the statistical uncertainties of the ocean waves (direction, height and period) and the influence this will have on a vessels response characteristics.
-is capable of interpreting, understanding and presenting results from a model test to colleagues and other partners.
