Abstract
At present article we work on physics and dynamics of iron particles in combustion chamber crossing the flame zones of (iron- air) suspension. In this article we focus on an iron dust free body diagram and forces on it. Gravity forces, drag force from gas and thermopherotic force are these forces on an iron particle. By existing of these forces on a particle, acceleration will be inducted to a particle in flame zones and by solving the differential equation of dynamic equation for a particle with continues boundary condition in velocity curve of dusts in dust- air suspension we can estimate the velocity profile across the flame zones. Theoretical estimation of velocity profile in this study has been compared to an experimental study on velocity and concentration profile of iron particles across the flame propagating through the particles cloud.
