Blended fuels such as biodiesel–diesel blends are being extensively used in practical devises such as engines. The burning characteristics of blended fuels are quite different than that of the individual fuels and need to be understood. In this study, a semiempirical analysis concerning the mass burning rate characteristics of biodiesel–diesel blends is presented based on the data measured using porous sphere experiments. Finally, a correlation for evaluating instantaneous burning rate of biodiesel–diesel blended fuels has been proposed for practical applications. Further, using this correlation, transient burning characteristics of blended biodiesel–diesel droplet in suspended mode have been studied for different blend compositions. Multiple modes of burning regimes are identified for the blended fuels.
