| Abstract: | In this study,based on a phenomenological multi-zone spray combustion model and a soot concentration submodel,an in-cylinder multi-zone (multi-dimension) radiavtive heat transfer model has been established.Using the Monte-Carlo simulation model,the distribution of radiative heat flux on the walls of the combustion chamber of a G4135 direct injection diesel engine has been calculated and analyzed. |
