Indeed, when viewed with a 20-inch scope at 175x, some of the diffuse plume structure
visible is suggestive of the appendages of some description of cosmic crustacean or starfish.
Related to the overall lower mixture density, it would appear that the RANS simulation produces a more diffuse (less dense) plume structure
than the LES simulation despite the fact that the input cone-angle is much smaller (9[degrees] compared to 25[degrees]).
Ultimately, hole inclination, needle lift and L/D (among other parameters) will have a greater influence on the plume structure
Atema at the Marine Biological Laboratory in Woods Hole, the behavior of a robot told us something unsuspected about the plume structure
(Grasso et al., 1996b).
The main emphasis was on the mixing process as it affected the plume structure
As the simplest observation of plume structure
in the [Z.sub.H] data above, the turrets of reflectivity in the Dereel event (lines A-D in Fig.
The most critical change in thinking has been an abandonment of diffusion models of odor plume structure
as a way to examine stimulus concentration.
The design of the system proved adequate to move quickly and easily from different locations around the fires in order to monitor the plume structure
and fire behavior from the needed angles and lines of sight.
The most detailed studies that have attempted to measure fluid dynamic conditions, odor plume structure
, and resultant orientation behavior have involved moths, crabs, and lobsters.
Although salt and ethanol diffuse differently than food odors at the molecular scale, we observed no visual differences in plume structure
between odor plumes and ethanol-salt plumes.
A stable plume structure
permits direct binary comparisons of chemical concentration inside and outside the plume, to guide movement lateral to flow.
All deployments were in California with the exception of a single exploratory airborne campaign that used the University of Wyoming King Air (UWKA) to observe plume structures
during a large wildfire in Idaho (ID).
