Course description and aims

This course focuses on basic concepts of viscous flow and its applications. Topics include fundamentals of viscous fluid, Navier-Stokes equations, Reynolds number, exact solutions of Navier-Stokes equations for parallel flows such as Couette-Poiseuille flow and Hagen-Poiseuille flow, Stokes's approximation, Oseen's approximation, boundary layer, Compressible flows. By combining lectures and exercises, the course enables students to understand and acquire the fundamentals of viscous fluid which are important for developments of real applications in mechanical engineering.

Fluid mechanics is one of the most important basic science in mechanical engineering. Following to ‘Fundamentals of Fluid Mechanics’, this lecture focuses on viscous fluids which appears in real worlds. By combining lectures and exercises, the course enables students to understand and acquire the fundamentals of viscous flow.

Student learning outcomes

By the end of this course, students will be able to:
1) Understand and derive governing equations of viscous fluid.
2) Acquire exact solutions of Navier-Stokes equations for several parallel flows.
3) Explain basic aspects of boundary layer
4) Explain Stokes's and Oseen's approximations
5) Explain friction and pressure drag forces and lift force.
6) Explain basic aspects of compressible flows

Keywords

Viscous fluid, Navier-Stokes equations, Reynolds number, Parallel flows, Couette-Poiseuille flow, Hagen-Poiseuille flow, Boundary layer, Stokes's approximation, Oseen's approximation, Drad force and Lift force, Compressible flows

Competencies that will be developed

✔ Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills

Class flow

The course is taught in lecture style. Exercise problems will be assigned every 2 or 3 classes. Required learning should be completed outside of the classroom for preparation and review purposes. Classes will be conducted live on the 1st and 2nd days (1st to 4th classes), and face-to-face on the other days. In the case of the live type, it may suddenly switch to the on-demand type depending on the live connection situation. The latest information will be communicated and published via T2SCHOLA.
