This course provides extensive topics on the dynamical aspects of fluid flows based on the previous lecture, Hydrodynamics1.
The students will learn the fundamental elements of fluid motion including shear, rotation, vortex, vorticity and circulation.
They will gain understanding on the basics of viscous fluid flows including laminar and turbulent flows, flow development,
velocity boundary layer, wall friction and pressure drop. They will learn the relation between fluid energy and loss.Furthermore,
the students will study on the forces acting on a body immersed in fluid. They will also learn applications of these knowledge
to rather practical flow problems. Moreover, knowledge of the students will be reinforced in terms of basic dynamics of fluid
treated in the Hydrodynamics1 and will be lead to the next lecture, Fluid Mechanics 1. From time to time, the students will
learn English terms as well as Japanese terms.
