Abstract

The transient modeling of radiation effects on combustion of an isolated nonane and hexanol droplet in standard atmospheric conditions with finite rate chemistry has been performed. Transient effects have been included in a comprehensive manner by including initial droplet heating, variable liquid and gas phase properties and non-luminous gas radiations. Results show that gas radiations are important for determining various parameters in droplet combustion. Estimation of Planck's mean absorption coefficient is critical for non-luminous gas radiation modeling. Gas radiation suppresses gas, liquid and flame temperatures. The burning rate decreases in the presence of radiative losses with increasing initial droplet diameter.
