Control of Chaos in Combustion Reactions [PDF]

The Journal of Physical Chemistry A, 2000
The chaotic evolution in the combustion of CO in a well-stirred flow reactor is controlled experimentally using a modified form of the simple proportional feedback (SPF) algorithm. An unstable period-1 oscillation is stabilized through the imposition of small, appropriate perturbations which are calculated from the observed experimental response of the

Fast reaction nonpremixed combustion [PDF]

Progress in Energy and Combustion Science, 1986
Abstract Recent measurements in turbulent, single-phase, reacting flows are reviewed. Attention is confined to nonpremixed flows at the fast reaction limit, which is defined as conditions where rates of reaction are fast enough to maintain local equilibrium.
