The boundary layer along the fuselage, wings and tailplanes of aircraft will usually be laminar at the leading edge and will become unstable further downstream. Once the boundary layer has become unstable it will undergo transition to turbulence. Stability and transition can be considered as one of the most complex problems of fluid dynamics. The details depend on a number of parameters, such as the type of initial perturbations (e.g. free-stream turbulence level, wall roughness), Reynolds number, streamwise pressure gradient, and wall curvature. This report gives an overview of existing theory to compute and analyse stability and transition of boundary layers. It covers the classical linear stability theory up to recent developments, such as the Parabolized Stability equations.
