Abstract: Abstract This work is devoted to the investigation of the late stages of the laminar-turbulent transition process in a flat-plate boundary layer without pressure gradient. Similar to a turbulent boundary layer these stages are dominated by nonlinear flow dynamics and by the occurrence of coherent vortex motions in the boundary layer, which are far from being well understood, up to now. The work consists of two parts: a description of some salient features of the numerical method, and an account of some specific results of a numerical study of the flow randomization process in K-type transition that has been performed conjointly with a wind-tunnel investigation at the Technical University of Berlin.
