✦ Synopsis

Dynamics of combustion processes of n-heptane and i-octane have been studied with varying temperature and pressure by means of a jet stirred flow reactor (JSFR), in the range 450-850K and 1-12 atm.

Periodic or damped oscillatory cool flames, multistage ignitions, "'jumps," and slow combustion have been observed, and their regions of existence in the pressure/temperature plane have been mapped.

Results indicate that ignition of n-heptane is possible at low temperatures and it is not strongly dependent on pressure. The behavior observed with i-octane at low temperatures is strongly dependent on pressure and give rise to ignition at pressures above -8 atm. At high temperature, spontaneous ignition occurs in both hydrocarbons and at pressures above -4 atm is feebly dependent on pressure.
