Cool flames in space: experimental and numerical studies of propane combustion

A Scaling Analysis of the Effects of Natural Convection, when Sal’nikov's Reaction: P→A→B Occurs, Together With Diffusion and Heat Transfer in a Batch Reactor

“…Work has also been carried out on the other limiting case, where the transport of heat and mass is purely diffusive (Gray and Scott, 1990b). This diffusive limit corresponds to reaction occurring in microgravity, as studied experimentally by Pearlman (2000) and numerically by Griffiths (2001, 2002) and Fairlie et al (2005). More recently, numerical studies have investigated the influence of natural convection on Sal"nikov"s reaction.…”

The behaviour of Sal’nikov’s reaction, P → A → B, in a spherical batch reactor with the diffusion of heat and matter

“…This work examines the behaviour of Sal'nikov's reaction 4 , which is the simplest reaction to exhibit such oscillations. It should be noted, of course, that Sal'nikov's reaction is a considerable simplification of the mechanism governing cool flames, which includes chemical feedback through chain branching in addition to the thermal feedback present in Sal'nikov's model 5 . Nevertheless, Sal'nikov's reaction can provide useful insights into the interaction of thermokinetic oscillations and various transport mechanisms.…”

When do chemical reactions promote mixing?

“…Even the chemical reaction with the simplest mechanism of A  B can produce complex aperiodic oscillations [46], so that, provided there is feed-back of heat, the resulting oscillations can in principle lead to self-mixing. It is also worth noting that…”
