MODELING OF LAMINAR COMBUSTION WAVE-PROPAGATION IN REACTIVE GAS PARTICLE MIXTURES/

The ignition and deflagration wave propagation in an enclosed stoichio metric H-2/O-2 mixture enriched with a low mass fraction of carbonaceo us particles ignited via a temperature non-uniformity is studied using a one-dimensional numerical model. Different particle diameters, Volu me fractions, and reactivities are used to investigate their effects o n the combustion waves. Detailed chemical kinetics for H-2/O-2 are app lied for the gas phase. Particle phase reactions are calculated using measured reaction probabilities for heterogeneous carbon reactions. Bo th phases being modeled as continua, the governing equations are solve d using flux-difference-splitting schemes. A dynamically moving adapti ve grid is applied in order to resolve reaction zones correctly. Copyr ight (C) 1996 Elsevier Science Ltd.
