Effect of Porous on Premixed Co-Flow Organic Particles Cloud Combustion

At this analyis، the premixed co-flow flames propagation of the Organic Porous particles-cloud combustion is studied with considering uniform mixture of fuel and air. Because of size equality assumption of the porous particles، lycopodium particles at this research are assumed. This analysis framework is thermal-diffusion model with this assumption that the lewis number is unit and the strain rate is constant. Velocity profiles are intended as a function of x in the direction of flames propagation. The structure of the flame is presumed to be consist of a preheat vaporization zone، a reaction zone and a convection zone. The Zeldovich number، based on the gas-phase oxidation of the gaseous fuel is large and the heat loss is neglected. This analysis consists of the result for the effect of different porous on the flame temperature and flame location. The results is illustrating when porous increase، the accessible substance to yield a gaseous fuel is decreasing that will be cause to burning velocity decrease. Also، flame location go to low burning velocity zone and the solid fuel at flame location increase، that not vaporized. This is match to the governing physics and experimental results.
