Combustion Modeling of Lycopodium Particles by Assuming the Temperature Difference Between Gas and Particle

Authors

Abstract

In this paper, the effect of temperature difference between gas and particle in the structure of premixed flames propagation in combustible system, containing uniformly distributed volatile fuel particle, in an oxidizing gas mixture, is analyzed. In the present work, equations based on the premixed flames of organic dust are used and then required relations for gas and particle are derived. Consequently, governing equations and needed boundary conditions are applied and an analytical method is used for solving these equations. It must be said that the structure of the flame consists of a preheat zone, a reaction zone and a convection zone. Finally, the variation of dimensionless temperature of gas and particle, particle mass friction, equivalence ratio of gas and particle, flame temperature and burning velocity of gas and particle are shown in figures.
