Abstract

This piece of work seeks to address issues related to combustion of diesel fuel in light-duty engines, with an emphasis on bridging detailed chemical kinetics mechanism and Computational Fluid Dynamics (CFD). Numerical computation was undertaken by means of integrating CHEMKIN and FLUENT software. The computational effort was focused onto the Laminar Finite Rate model, incorporating a surrogate diesel fuel mechanism. Resulting effect on the formation of nitrogen oxides (NO_x) and soot, and computational expenses-related issues are of particular interest. Three dimensional simulations were deployed and the results generated were compared against experimental output. Current 3-D simulations attained showed predictive capabilities.
