Course description
This course is a continuation of 'Fluid Mechanics 1'. We learn fundamentals of boundary layer and turbulence theories. These theories are very important to design pipe lines and other fluid machines.
In this course, practical techniques such as tests in wind tunnels, flow measurement and visualization are also explained.
Purpose of class
The aim of this course is to learn basic knowledge about fluid dynamics and to acquire the ability to solve the problems related to fluid dynamics based on these knowledge.
Goals and objectives
  1. Students can evaluate velocity distribution in laminar boundary layer and boundary layer thickness by solving the Prandtl's boundary layer equation and Karman's momentum equation.
  2. Students can evaluate frictional resistance in turbulent flow in a pipe based on the Prandtl's mixing length theory.
  3. Students can solve the problems related to fluid dynamics based on these knowledge of practical techniques such as tests in wind tunnels, flow measurement and visualization.
  4. Students can evaluate frictional resistance and the Strouhal number in the flow around obstacles.
