The present course provides extensive topics on the dynamical aspects of fluid flows based on the previous course, Fluid Mechanics
1. The students learn the fundamental elements of fluid motion including translation, elongation/compression, shear and rotation.
They learn vorticity, circulation, and different types of vortex and their features. They gain understanding on the basics
of viscous fluid flows including laminar and turbulent flows, flow development, velocity boundary layer, wall friction and
pressure loss. They learn the relation between fluid energy and loss. Furthermore, the students will study on the forces acting
on a body immersed in a uniform fluid flow including flat plate boundary layer and forces working on the body. They also learn
applications of these knowledge to rather practical flow problems using Moody diagram. Moreover, knowledge of the students
is reinforced in terms of basic dynamics of fluid treated in the Fluid Mechanics1 and is lead to the next course, Viscous
Fluid Mechanics. From time to time, the students will learn English terms as well as Japanese terms.

The final score is evaluated based on intermediate examination (40%), final examination (50%) and report (10%). 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 understanding and classifying four elemental motions of fluid flows
and vortical motions in terms of vorticity and circulation, 2 understanding and applying the flow development and pressure
loss due to friction of viscous fluid in internal flows, 3 understanding and predicting the frictional behavior of internal
flows based on Reynolds number and hydraulic diameter, 4
understanding and applying the velocity boundary layer and related features developing over an object immersed in uniform fuid flow, 5 understanding and predicting the forces working on an object placed in a fluid flow.

There is no designated textbook in the course. The students can refer to any textbooks related to hydrodynamics and fluid
mechanics such as "introduction for Fluid Mechanics for Mechanical Engineers" by Kazuyasu Matsuo, Ohmsha (2007). The book
is well consistent with the contents in the Hydrodynamics 1 in the spring/summer semester, covering fundamental to advanced
contents and with technical terms in English. Further textbooks are available online as electronic books via ProQuest Ebook
Central through the SIT library.
Prerequisite knowledge
basic knowledge on mathematics (linear algebra, calculus, vector analysis), physics (dynamics) and basic of hydrodynamics (taught in Hydrodynamics1).
(The prerequisite knowledge will not be taught in this class. Those who do not have the prerequisite knowledge are advised not to enroll in this course.)
Supplement
Although the course requires the knowledge of Fluid Mechanics1, those who did not pass the Fluid Mechanics1 can take the course and obtain scores at the end. If they pass the pass criterion, they can receive the credits.
