Abstract

The combustion performance and emissions of liquid fuels are mainly influenced by the atomization of the
liquid fuel, the motion and evaporation of the fuel droplets and mixing of fuel and air. A reliable
description and simulation of spray combustion requires a detailed understanding of droplet ignition and
combustion. Recently, it has become apparent that an understanding of the mechanisms related to spray
combustion is the key to the development of non-polluting and high performance devices. In this study
liquid droplets of Toluene is taken into consideration and their burning characteristics are investigated for
different combustor geometries and droplet sizes. Non-adiabatic presumed probability density function
(PPDF) model is used with high Reynolds number k-ε model. Droplet breakups are handled with Reitz-
Diwakar model. Preliminary investigation shows that droplet size, inlet pattern and oxidizer temperature
have profound effect on combustion temperature distribution and pollutant formation.
