Sažetak
In order to meet the reduction of carbon dioxide emissions, biofuels are imposed as an alternative to conventional fuels in the transport sector. Biofuel made from plant-derived waste, called biodiesel, has shown to positively impact total carbon dioxide emissions and have a positive environmental impact on waste recovery. One of the great advantages of biodiesel is its applicability in standard internal combustion engines when blended with conventional fuels. Such mixtures require very little or almost any additional modifications to the engines. Computational fluid dynamics combined with chemical kinetics is often employed to investigate combustion and auto- ignition properties of new fuels, including biofuels. This thesis will present a brief overview and generation classification of biofuels, describe the fundamental equations of computational fluid dynamics and the equations of modelling chemical kinetics using the chemical mechanism of fuel combustion. Additionally, numerical simulations of the combustion process of different generations of biodiesel were performed in the computational fluid dynamics software AVL- FIRE™. Simulations were verified by comparing the obtained simulation data for n-heptane, a substitute for diesel fuel, to experimental data provided by AVL GmbH Graz. Biodiesels made from four different plant-derived feedstocks were compared under four operating conditions in various diesel-biodiesel blends.
