POD Study of Turbulent Boundary Layer Structures

ORAL

Abstract

3D POD is performed on a recent DNS turbulent boundary layer simulation (Wu \& Moin, Phys. Fluids, 2010). The modes of various scales are examined. Dominant modes include structures consistent with the inclined ramps commonly observed in turbulent boundary layers. POD modes are examined to interpret the spatial organizations of the structural elements.
