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.
