Abstract

Diesel engine performance and emissions is strongly couple with fuel atomization and spray processes, which in turn is strongly influenced by injector flow dynamics. This paper describes simulation of combustion characteristics under high ambient and high injection of biodiesel combustion by using CFD simulation. This study reviews the effect of temperature and pressure on the spray characteristics, as well as fuel-air mixing characteristics. Experiments were performed in a constant volume chamber at specified ambient gas temperature and pressure. This research continues using CFD software. A computational fluid dynamics (CFD) model of an internal engine has been developed using the commercial CFD package ANSYS 14.5. The method of the simulation of real phenomenon of diesel combustion with optical access rapid compression machine is also reviewed and experimental results are presented. Three dimensional models and sub-models are created using Solidworks software before being imported into ANSYS. The increases in ambient pressure inside the chamber resulting in gain of spray area and wider spray angle. Thus predominantly promotes for a better fuel-air mixing
