Recognizing that previous experimental studies on constant-pressure, outwardly propagating, spherical flames with imaging capability were limited to pressures less than about 5 atm, and that pressures within internal combustion engines are substantially higher, a novel experimental apparatus was designed to extend the environmental pressure to 60 atm. Results substantiate previous observations of the propensity of cell formation over the flame surface due to hydrodynamic and diffusive-thermal instabilities and provide convincing evidence that wrinkled flame is the preferred mode of propagation in hydrogen/air mixtures in environments with pressures above only a few atmospheres. It is further shown that, by using helium as the diluent, and by reducing the oxygen concentration of the combustible, diffusional-thermal instability can be mostly suppressed and the hydrodynamic instability delayed. Stretch-free laminar flame speeds were subsequently determined for such smooth flames up to 20 atm and were compared with the calculated values, allowing for detailed chemistry and transport.

“…This fine resolution level is needed to adequately resolve the flame structure. The initial condition consists of the superposition of the velocity field induced by a periodic row of vortex pairs, with temperature, density, and mass fraction distributions of a steady-propagating, one-dimensional premixed flame computed with CHEMKIN [20,21]. We use the GRIMech 1.2 [22] mechanism with 32 species and 177 reactions.…”
