Kurzfassung
The formation and development of a turbulent spot in a laminar boundary layer flow is governed by the self-organization of generic substructures like hairpin-vortices and spanwise alternating wall bounded low- and high-speed streaks which effectively produce new turbulent flow structures out of the oncoming laminar flow reaching the spot at the rear edge. Although the main flow structures are identified and the exchange topologies in wall normal directions inside the spot are depicted roughly the principle growth mechanism of the turbulent spot itself is still not fully understood. The analysis of this growing process would also help to understand the function of very similar structures for the turbulent exchange in fully developed turbulent boundary layer flows.
