One of the most essential inherent characteristics a combustible mixture is laminar burning velocity. Because its relevance, many methods for measuring flame velocity have been devised. advanced procedure was used to derive in constant volume vessel blends iso-octane and n-heptane/air mixtures this study: particle imaging velocimetry. Based on precise flow field with vectors, velocimetry (PIV) ...

We analyze the sensitivity of the flame propagation in a Chandrasekhar mass white dwarf to initial conditions during the subsonic burning phase (deflagration), using 2D simulations of the full WD. Results are presented for a wide variety of initial flame distributions including central and off-center single point and multi-point, simultaneous and non-simultaneous, ignitions. We also examine the...

The production of the fire suppressant CF3Br has been banned, and finding a replacement with all of its desirable properties is proving difficult. Iron pentacarbonyl has been found to be up to several orders of magnitude more effective than CF3Br, but it is flammable and highly toxic. Ferrocene [Fe(C5H5)2], which is much less toxic and flammable than Fe(CO)5, can also be used to introduce iron ...

The kinematic models for perturbed flames from [7, 6] are extended to account for flames with arbitrary cone angles and a burning velocity with non constant direction. This extension improves the description of the front close to the boundary and, consequently, the behaviour of the flame response to velocity perturbations. PACS: 43.28.Kt; 47.75.Pq; 02.60.Cb

Currently, the use of fossil fuels is very high and existing nature reserves are rapidly depleted. Therefore, researchers turning their attention to find renewable that have a low impact on environment, replace these fuels. Biogas low-cost alternative, sustainable, fuel worldwide. It can be produced by decomposition vegetation or waste products human animal biological activity. This process per...

We calculated models of massive AGB stars with a self-consistent coupling of timedependent mixing and nuclear burning for 30 isotopes and 74 reactions. Overshoot with an exponentially declining velocity field was considered and applied during all stages of evolution and in all convective regions. Very efficient 3 dredge-up was found even overcompensating the growth of the hydrogenexhausted core...
