Teaching Method
Outline:
The purpose of studying fluid dynamics is to understand the flow phenomena built on the principles of dynamics and to solve real-world problems and make new creations through logical and experimental observations.
The aim of this course is to understand basic knowledge of fluid dynamics, to gain insight into the physical phenomena associated with fluids, and to gain the ability to apply engineering to fluid machinery and other applications. Specifically, students will understand what we call hydrodynamics, and gain an engineering sense of fluid motion, as well as how to calculate the basic fluid problems necessary for mechanical design.
Style:
The class focuses on lectures using slides and blackboards, and there will be work and exercises by each unit. In order to achieve the goal, try ensure to follow the questions and answers and work in class as matter of fact, as well as the exercises assigned in each class. Go back to the basics if having difficulty to understand, and ask questions to the faculty and learn from each other among students.
Notice:
(1) As this course uses the content from the dynamics (Science Ⅰ(Grade 1), Science Ⅲ a (Grade 3), Industrial Dynamics (Grade 3)), and mathematics (Mathematics Ⅰ to Mathematics Ⅲ), it is advised to review those subjects as appropriate.
(2) Learn not only about fluid dynamics, but also how mathematical descriptions relate to actual fluid phenomena. In other words, not only taking notes during the class, students need to use their thoughts when asking questions, and need to work actively together at group works.
(3) Activity instructions and answers will be distributed on the web. Instructions for submitting and obtaining answers will be provided at the beginning of the class.
This course's content will amount to 90 hours of study in total. These hours include the learning time guaranteed in classes and the standard self-study time required for pre-study / review, and completing assignment reports.
Students who miss 1/3 or more of classes will not be eligible for a passing grade.
