Introduction to Boundary Layers

Introduction to Boundary Layers. Instructor: Dr. Rinku Mukherjee, Department of Applied Mechanics, IIT Madras. This course introduces the concept of a boundary layer and the physical concepts of boundary layer thickness, displacement thickness, momentum thickness and friction drag. It derives Prandtl's Boundary Layer Equations for laminar boundary layers from the basic Navier-Stokes equations and discusses their exact solutions. It discusses how a laminar boundary layer transitions to turbulence and separates. It also discusses thermal boundary layers. (from nptel.ac.in)
