Experimental Observation of Ordered States
of Cellular Flames
Figure 1.
a) a steady flame; b-c) a single ring of b)five and c) six cells
observed at 1/3 atmosphere; d-j) a ring of outer cells
surrounding d) one, e) two, f) three, g) four, h) five,
i) six, and j) seven inner cells;
k) three inner cells acting as a nucleating center for a hexangonal
lattice; and l) a rhombic array of cells which appears
for a short time after an abrupt change of the flow parameters
from a steady flame.
