Abstract:
Combustion has been considered an energy source and factor represent growth and technology a community in human history. Combustion is known as the intersection of the fields of fluid mechanics, thermodynamics, heat transfer and chemical reactions.
In this thesis tried pluralization how combustion modeling to form of discrete and random.
Knowledge of solid particles combustion Is derived from wave propagation in the form of discrete that due to its importance requires the extension and development in the field of science and engineering such as aerospace, fuel and energy, and driving systems and also explosion safety in mines and silos and forest fire and even biology and medicine, of both analytical and empirical.
In here, it is presumed that first the moisture content of the solid particles evaporate, then the dried particles vaporize to yield a gaseous fuel. The flame structure is divided into six zones:
first heating, drying, second heating, volatile evaporation, flame and post-flame zones.
By consideration the full effects of the environment on the behavior of the particle, elevated and comprehensive modeling is provided in this regard.
In this dissertation, the effect of radiation was considered on dust particles combustion in the six zones model In addition to the effects of radiation on combustion to studied, The analysis have closer to reality. also in this modeling tried to study flame structure viewpoint microscopic, accordingly the heat model is based on discrete combustion of dust particles for this purpose reaction source is considered to form discrete. as well as random model is proposed with lamination to consider fuel that each of the layers properties is different with another.
Keywords: discrete modeling, random modeling, radiation, damköhler numbers, lycopodium, counterflow.
