Discrete multicomponent model for biodiesel spray combustion simulation.

Highlights: [•] Discrete and continuous multicomponent liquid models are calculated from the real biodiesel properties. [•] Continuous multicomponent liquid model is employed for diesel spray simulation. [•] The predicted spray-combustion characteristics of diesel and biodiesel are compared with the experimental measurements. [•] The discrete model performs better than the continuous model in predicting the spray-combustion characteristics of the biodiesel flame. [•] Effects of the relative abundance and the relative volatility of biodiesel fuel components are highlighted. [ABSTRACT FROM AUTHOR]
