Transient Effects in the Droplet Combustion Process in an Acoustically Perturbed High Temperature Environment

Abstract

This analysis discusses the effects of acoustic perturbations and chemical reactions on droplet combustion when the ambient temperatue is larger than the adiabatic flame temperature. The acoustic field is simulated by sinusoidal perturbations. The chemical reaction occurs as a small rate, a consequence of the condition of the ambient temperature being larger than the adiabatic flame temperature. The results show that the vaporization rate increases due to the presence of the acoustic field and increases with increasing Damkohler number.

• Droplet combustion
• diffusion flame in “premixed flame regime”
