the rayleigh-taylor instability
|
Shown in these figures are composites of several
different renderings of the denisity
field arising from the simulation of the
Rayleigh-Taylor instability - a fundamental
instability which occurs whenever light
fluid is accelerated into heavy fluid and
which gives rise to turbulence and mixing.
An isosurface of density has been
superposed on the three dimensional grid
used in the simulation. At each point in
the grid the local density is indicated via
a small sphere color coded by the density. The
simulation (with a resolution of 512 points in each
direction) was performed on the LLNL ASCI Blue
machine by Dr. A. Cook of LLNL. The data
sets were then analyzed at Caltech.

isosurface for density=2 of two liquids of density
1 and 3 during time sterp 0.2240 of reaction.

isosurface of density=1.25 of time step 0.2280,
intersected with orthagonal slice with color index
of density.

isosurface of density=1.41 of time step 0.2280,
intersected with orthagonal slice with color index
of density, inmersed in rendered field of point
density samples evenly spaced.

isosurface of density=2.65 of time step 0.2280,
intersected with orthagonal slice with color index
of density.
