Abstract

The innovation in software analysis and various available programming facilities have urged the designers at various levels to do indispensable calculations for engine flows. Presently, the 3-D analysis approach is under practice to do simulations for various parameters involving engine operations using various softwares, “Fluent” being the trendiest at the moment for CFD modeling. The present work involves CFD modeling of diesel fuel sprays at a specified angle with cylinder axis. Fuel spray modeling includes sub-models for aerodynamic drag, droplet oscillation and distortion, turbulence effects, droplet breakup, evaporation, and droplet collision and coalescence. The data available from existing published work is used to model the fuel spray and the subsequent simulation results are compared to experimental results to test validity of the proposed models.
