“…This arrangement is suitable for studying Sal'nikov's reaction in the well-mixed limit; however, it is not suitable for cases that are not spatially uniform. This reaction has also been studied numerically in the well mixed and zero gravity extremes 24,25 as well as when natural convection is present [11][12][13][14][15] . The reaction between hydrogen and chlorine, using similar experimental techniques, has also been used as a model of Sal'nikov's reaction 24 .…”

“…This boundary condition differs from that in the previous 1-D studies 17,18 , which assumed zero heat flux at the boundary of the region studied. The conditions used in this study are however the same as those studied by Fairlie and Griffiths 24,25 . The boundary conditions used are therefore:…”

“…Numerical studies 24,25 of Sal'nikov's reaction in a purely diffusive system have considered some aspects of the temporal development of oscillations when the reaction occurs in a spherical vessel, with a fixed wall temperature; that situation is similar to the experimental configuration described by Pearlman 16 .…”

The behaviour of a simple chemical reaction, occurring with the release of heat in a closed batch reactor, is considered for the situation when matter and heat are transported only by diffusive processes; thus, the reacting fluid has negligible velocity, so that heat transfer is by thermal conduction. The reaction is Sal'nikov's, which consists of two, consecutive first-order steps, producing a product B, from a precursor P, via an active intermediate A, in P→A→B. The first of these steps is assumed to be thermoneutral, with zero activation energy, whilst the second is exothermic, with an appreciable activation energy. These features make Sal'nikov's reaction the simplest to display thermokinetic

Stroboskopgemische sind pyrotechnische Zusammensetzungen, die ein oszillierendes Verbrennungsverhalten zeigen; eine Dunkel‐ und eine Leuchtphase alternieren periodisch. Der Stroboskopeffekt wird in verschiedenen Bereichen, aber hauptsächlich in der Feuerwerksindustrie und im militärischen Bereich angewendet. Alle Stroboskopgemische, die in der Literatur beschrieben werden, wurden durch systematisches Ausprobieren entdeckt und die zugrundeliegenden Mechanismen bleiben ungeklärt. Viele oszillierende Systeme wurden beobachtet, und es wurden Theorien entwickelt, die auf chemischen Prozessen oder physikalischen Prozessen beruhen, um ihr instabiles Verhalten aufzuklären. Diese Systeme werden mit experimentellen Beobachtungen an Stroboskopgemischen verglichen.

Strobes: Pyrotechnic Compositions That Show a Curious Oscillatory Combustion

Strobes are pyrotechnic compositions which show an oscillatory combustion; a dark phase and a flash phase alternate periodically. The strobe effect has applications in various fields, most notably in the fireworks industry and in the military area. All strobe compositions mentioned in the literature were discovered by trial and error methods and the mechanisms involved remain unclear. Many oscillatory systems such as Belousov-Zhabotinsky reactions, cool flames, self-propagating high-temperature synthesis have been observed and theories developed to elucidate their unstable behavior based on chemical interactions or based on physical processes. These systems are compared to experimental observations made on strobe mixtures.
