Boundary layer theory is studied in all introductory courses in fluid mechanics. However, this theory is very complex for laminar and turbulent flow. The outcome of the subject is to explore all relevant phenomenons of laminar and turbulent boundary layers starting from Prandtl up to today.

The outcome of the course is to learn all the relevant boundary layer phenomena and master the balance equations of mass, momentum and energy with special applications to the boundary layer theory. Special emphasis is placed on the knowledge of the specific mathematical methods applied for boundary layer calculation.

Basic equations of fluid mechanics. Assumptions of boundary layer theory - Prandtl equations for plane incompressible flow. Equations of boundary layer theory. Karman-Polhauzen method. Similar solutions. Exact solution for laminar boundary layer at the flat plate. Folkner-Scan solution. The transition from laminar to turbulent flow. Effects of pressure gradient, noise, wall roughness etc. Experimental methods of boundary layer flow. Numerical methods for solutions of boundary layer equations.
