Course description
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, the course reinforce the basic dynamics of fluid treated in the Hydrodynamics1 and lead to the next lecture, Fluid Mechanics 1. From time to time, English terms will be provided in the lecture held in Japanese language.
Purpose of class
1. To understand the difference between shear and rotation
2. To be able to identify different types Vortices based on vorticity and circulation
3. To understand the function of viscosity, flow development, friction loss and pressure drop in an internal flow.
4. To be able to identity and explain the forces acting on a body placed in a fluid flow.
5. To be able to apply the basic knowledge learned in the above.
Goals and objectives
  1. To understand and to be able to apply the vorticity and circulation on vortical flows.
  2. To understand the fundamental features of viscous fluid flows and to be able to apply the relation between the wall friction and pressure drop in an internal flow.
  3. To understand the stresses acting on a body placed in a fluid flow and to be able to explain the stresses.

Evaluation method and criteria
The final score is evaluated based on practice (15%), assignments (25%), intermediate exam (30%) and final exam (30%). Credit will be given only when the score is equal or over 60% out of 100 % in total. Successful credit acquisition requires the following conditions to be satisfied. The student is capable of 1. To understand and to be able to apply the vorticity and circulation on vortical flows, and besides, 2. To understand the fundamental features of viscous fluid flows and to be able to apply the relation between the wall friction and pressure drop in an internal flow, and besides, 3. To understand the stresses acting on a body placed in a fluid flow and to be able to explain the stresses.
