Class Objectives
/Class Outline
The destination of studying fluid mechanics is to understand the governing laws deeply and to be able to apply such laws to practical cases.  In this class, you learn mainly the latter by solving some fundamental problems.
(1) To understand how to calculate forces on solid body.
(2) To understand how to treat irrotational flows.
(3) To understand the influences of body shape on forces on solid body.
(4) To understand the concept of the boundary layer. 
Class Schedule (1)  Introduction : Review of Fluid Dynamics (2T)
(2)  Vorticity, Divergence
(3)  Basic Equation(1) : Mass conservation, Acceleration of fluid
(4)  Basic Equation(2) : Euler Equation/Navier-Stokes Equation, Bernoulli's principle
(5)  Irrotational Flows(1) : Basic Velocity Potential and Stream Function, Cauchy-Riemann Relation
(6)  Irrotational Flows(2) : Application of Velocity Potential and Stream Function
(7)  Irrotational Flows(3) : Flow around a cylinder
(8)  Irrotational Flows(4) : Fluid force and flow fields
(9)  Basic of viscous flow(1):Couette/Poiseuille Flow
(10) Basic of viscous flow(2):Hagen-Poiseuille Flow, Definition of Boundary layer
(11) Boundary-Layer Theory(1):Boundary layer thickness
(12) Boundary-Layer Theory(2):Velocity in Laminar Boundary layer
(13) Boundary-Layer Theory(3):Momentum equation, Shear Stress on flat wall, Examples of boundary layer
(14) Basic of turbulent flows(1):Separation and vortex, Difference between laminar and turbulent flows
(15) Basic of turbulent flows(2) : Reynolds Average, Law of wall
