Flow properties, such as vorticity and strain rates, are obtained for the entire region, and other properties, such as mean turbulence and other higher-order flow statistics, can be calculated.
Dietrich and Lin (1994) noted the influence of Caribbean eddies on the vorticity of the LC and eddy shedding.
Using the 3-D data, we determined the position of the finlets during a critical portion of the stroke cycle when, as predicted by the vorticity enhancement hypothesis described above, the finlets may redirect water flow towards the caudal fin vortex.
The intrusions of the western branch of the slope current into the canyon, have been explained in terms of the conservation of potential vorticity by Maso er al.
Evolution, functional perfection, insect flapping flight, suboptimality, vorticity.
The reverse process--the generation of counterclockwise vorticity and downslope transport of it--appears in the off-shelf phase of the tidal current.
The temporal and spatial characteristics of rear velocity field and vorticity field are contrasted to the PIV testing data as well.
The vorticity is coupled with high turbulence intensity, in excess of TI = 45% [12], and low axial velocity.
I'll add here that meteorologically we often see all sorts of microscale circulations along outflow boundaries, like vertical vorticity centers that further concentrate the winds and cause strong shear patterns.
5L] denotes the absolute vorticity in the flow, averaged spanwise at x = 0.
