Turbulent/non-turbulent Interface in Transitional and Turbulent Boundary Layers


Abstract eng:
The turbulent/non—turbulent (T/NT) interface in a transitional boundary layer is examined using direct numerical simulation (DNS) flow field. The interface is identified using the local vorticity, and its statistical properties are reported. Similarities between the turbulence spots and fully turbulent region are evaluated using conditional sampling. In addition, the modulation of the interface by large- scale motion (LSM) is investigated with the aid of a streak detection algorithm.
