Structure of turbulence in the marine atmospheric surface layer
… air-sea interface. It is speculated that these motions may also be associated with large scale organized motions in wall bounded turbulent shear flows. The effort aimed at elucidating the physics underlying such structures would be invaluable in contributing to our understanding of the air-sea …

Measurements of the structure of urban-type boundary layers
… size. Quadrant analysis showed the instantaneous sweep motions found near the rough surface intermittently producing large percentages of the local shear stress. Spatial correlation analysis of the instantaneous field data collected with particle image velocimetry revealed long, …

Characteristics of Coherent Structures in Marine Atmospheric Surface Layer
… similar coherent structures include ejections, sweeps, shear layers, transverse vortices, and combined events of the shear layers and transverse vortices. Besides these similar coherent structures, there exist the plume and downdraft motions in the unstable marine atmospheric surface layer. It …

Some Features of Tip Gap Flow Fields of a Linear Compressor Cascade
… low speed streaks outward from the wall and the sweeps of high speed streaks inward toward the wall are the dominant coherent motions. The octant analysis for the three-dimensional turbulent boundary layer in the tip gap shows that the dominant octant events are partially different from those in …

Investigation of horizontal meteorological structures in comparison to turbulent structures at a forest edge
… variation could be observed for ejections and sweeps, with strong ejection motions during daytime (updraft) and strong sweep motions during nighttime (downdraft). The thermal updraft during daytime could be attributed to the highest temperatures occurring near the forest edge (1.5 K warmer than …
