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, 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. In this year, lectures will be held face-to-face and examinations will be held twice face-to-face.

Evaluation method and criteria
The final score is evaluated based on report assignments (40%), examinations (60%). 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 the vorticity and circulation and to be able to identify different types of vortex motion, 2.To understand the development of internal flow and to be able to calculate the relationship between wall friction and pressure drop, 3.To understand the relationship among the fluid energy, pressure loss and wall friction and to be able to calculate the friction at certain flow conditions, 4.To understand the velocity boundary layer of external flow and to be able to predict the friction of fluid flow over flat plate, and, 5.To understand forces acting on a body placed in a fluid flow and to be able to predict them under certain conditions

Textbooks and reference materials
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.
Prerequisites
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 Hydrodynamics1, those who did not pass the Hydrodynamics1 can take the course and obtain scores at the end. If they pass the pass criterion, they can receive the credits.

Concerning the course format, the course was held on-demand in 2020, but the course will be held face-to-face (with live streaming and video recording) in 2021. The examinations will be held face-to-face in Omiya Campus. Those who cannot attend the examination in Omiya can take the examination face-to-face in Toyosu campus on Saturday.
