Query: Arrays of coupled chemical oscillators   Oscillating chemical reactions result from complex periodic changes in the
concentration of the reactants. In spatially ordered ensembles of candle flame
oscillators the fluctuations in the ratio of oxygen atoms with respect to that
of carbon, hydrogen and nitrogen produces an oscillation in the visible part of
the flame related to the energy released per unit mass of oxygen. Thus, the
products of the reaction vary in concentration as a function of time, giving
rise to an oscillation in the amount of soot and radiative emission.
Synchronisation of interacting dynamical sub-systems occurs as arrays of flames
that act as master and slave oscillators, with groups of candles numbering
greater than two, creating a synchronised motion in three-dimensions. In a ring
of candles the visible parts of each flame move together, up and down and back
and forth, in a manner that appears like a "worship". Here this effect is shown
for rings of flames which collectively empower a central flame to pulse to
greater heights. In contrast, situations where the central flames are
suppressed are also found. The phenomena leads to in-phase synchronised states
emerging between periods of anti-phase synchronisation for arrays with
different columnar sizes of candle and positioning.
