Empirical soot formation and oxidation model

Abstract

Modelling internal combustion engines can be made following different approaches, depending on the type of problem to be simulated. A diesel combustion model has been developed and implemented in a full cycle simulation of a combustion, model accounts for transient fuel spray evolution, fuel-air mixing, ignition, combustion, and soot pollut ant formation. The models of turbulent combustion of diffusion flame, apply to diffusion flames, which one meets in in dustry, typically in the diesel engines particulate emission represents one of the most deleterious pollutants generated during diesel combustion. Stringent standards on particulate emission along with specific empha sisonsize of emitted particulates have resulted in increased interest infundamental understanding of the mechanisms of soot particulate formation and oxidation in internal combustion engines. A phenomenological numerical model which canpredict the parti clesize distribution of the soot emitted will be very use ful in explaining the above observed results and will also be of use to develop better particulate controltechniques. A diesel engine chosen for simulation is a version of the Cater pillar 3406. We are in terested in employing a standard finite-volume computational fluid dy namics code, KIVA3V-RELEASE2.
