| Abstract: | In this paper, the analytical study of effects of radiation and non-unity Lewis number on the laminar premixed flames of organic dust clouds has been done. The research is focused on a combustion model for premixed flames and the flame structure is composed of preheat-vaporization, narrow reaction and finally the post-flame zone. The normalized governing equations with help of boundary and matching conditions are solved by perturbation method. The results show that increasing equivalence ratio and decreasing Lewis number are resulted in the increase of flame temperature and burning velocity. For the sake of this model validation, fuel conversion is compared by published experimental data and shows an acceptable agreement. |
