The image below is a collage by Jim Leith of the temporal evolution
of the interface in Rayleigh-Taylor mixing, as computed in a Lattice-Boltzmann
simulation by Dr. Timothy T. Clark, Complex Systems, Los Alamos National
Laboratory. Physically, the interface region is created and grows from
an initially quiescent non-mixed state following sudden acceleration downward
so that heavier fluid overlies lighter fluid.
