Unformatted text preview: Lecture 1 – Marine Hydrodynamics Lecture 1 Introduction Marine Hydrodynamics is the branch of Fluid Mechanics that studies the motion of incom- pressible ﬂuids (liquids) and the forces acting on solid bodies immersed in them. Marine hydrodynamics is a large and diverse subject and only a limited number of topics can be covered in an introductory course. The topics that will be covered throughout the semester include: • Model testing and similitude • Interaction between bodies and ideal ﬂuids • Viscosity and boundary layers • Effect of waves on resistance and ship motion Why study Marine Hydrodynamics? Studying Marine Hydrodynamics provides a greater understanding of a wide range of phe- nomena of considerable complexity involving ﬂuids. Another benefit is that it allows pre- dictions to be made in many areas of practical importance. 1 2.20 - Marine Hydrodynamics, Spring 2005 2.20 Fluids vs. Solids In brief, Fluid Mechanics studies the kinematics and dynamics of a group of particles with- out having to study each particle separately. Most of us have taken some courses on solids or related to solids. Even those who haven’t can get an intuitive feeling about some physical properties of a solid. Thus a comparison of solids and ﬂuids will give some guidelines as to which properties can be translated to ﬂuids and on what terms....
