文摘

Effect of cell formation on burning speed and flame surface area is investigated. A new developed non-dimensional number called cellularity factor is introduced. Cellular burning speed and mass burning rate are calculated using differential based multi-shell model. Flame instability is studied using thermo-diffusive and hydrodynamics effects. Power law correlations are developed for cellular burning speeds and mass burning rates.
