Abstract
In order to clarify spray combustion mechanism, numerical calculation on flame propagation of a fuel droplet array was conducted. Numerical results were compared with microgravity experiments, and revealed details of the propagation process. However, most of those researches were considered in stillness atmosphere. In actual spray combustion, droplets are influenced of the circumference air current. It is not yet clear that the influence which a circumference air current has on flame propagation, In the present paper, the effect of forced convection on flame propagation of a fuel droplet array was discussed by numerical calculation.
