Course Objective

This course aimsa at strengthening and broadening graduate students' background knowledge on hydrodynamics in ship and marine applications. Main topics covered in the semester include basic concepts and equations, ideal fluid flow, vorticity dynamics, potential theory, and lifting surfaces.

Learning Outcomes of the Course Unit

1   To analyze and assess a ship form from the point of view of maneuvering and steering characteristics and seakeeping
2   To have an outlook to steering devices and roll stabilization techniques
3   To be able to apply basic principles involving marine hydrodynamics in simple mathematical problem solving involving marine structures/vehicles
4   To design and analyze simple marine systems
5   To use computer software analysis, modeling and design of marine systems
