Course Objectives In this course, the concept of boundary layer and the relevant physical concepts (boundary layer thickness, displacement thickness, momentum thickness and friction drag) will be introduced. Prandtl’s boundary layer equations for laminar boundary layers will be derived from the Navier-Stokes equations and their exact solutions will be discussed. Transition of a laminar flow to turbulence and thermal boundary layers will also be discussed.
Course Learning Outcomes The students who succeeded in this course;
  • learn the parameters characterizing a boundary layer,
  • be able to apply Prandtl’s boundary layer equations to a flat plate and some more general geometries,
  • be able to obtain similarity solutions to boundary layer equations
  • learn the basics of thermal boundary layers,
  • be able to develop a numerical code to solve simple boundary layer problems.
Course Content General information and governing equations for viscous flows. Laminar boundary layer equations for incompressible flows. Boundary layer separation. Boundary layer on straight wall. Integral momentum and energy equations for boundary layers. Turbulent boundary layer for incompressible flows. Turbulence modelling. Flow separation and control.
