Abstract:
Application of dust cloud combustion in propulsion systems and safety from fire and explosion in industrial environment, made this branch of combustion science, an attractive subject to scholars and scientists, counterflow configuration is feasible and would be applied under control of user. So, it would be applicable in modeling and experiments. In the other hand, mathematical and theoretical modeling of counterflow configuration facilitates the experiments on it. Counterflow configuration would be applied in two models: premixed and non-premixed. Study on this configuration, provides the evaluation of combustion specification of premixed and non-premixed counterflow configuration. Aforementioned, the applications of dust cloud combustion in counterflow configuration at industries, give a good motivation for theoretical modeling of that.
In this thesis, the first and second chapters consist of a review on literature in dust cloud combustion and counterflow flame. The third and fourth chapters, focused on modeling of
non-premixed of a counterflow configuration of dust clouds with a front drying and vaporization and drying and vaporization zone. In this counterflow configuration, it is assumed that dust cloud as fuel and air as oxidizer, move toward stagnation plane from two opposed jet. It is assumed that the dust cloud as fuel, first drying then vaporize to from a gaseous fuel to oxidizer with air. In chapter five, the work concluded and suggestions for future works, proposed.
