Biodiesel derived from waste cooking oil (WCO) and animal fats is a promising alternative to fossil fuels, offering environmental benefits renewable energy potential. However, detailed understanding of its combustion characteristics at the droplet scale essential for optimizing practical application. This study investigates behavior biodiesel–diesel blends (B5, B10, B15, B20, B25, B50, B75) neat fuels (B0 B100) by analyzing rates, pre-ignition time, burning morphology, puffing characteristics. The results demonstrate that biodiesel concentration strongly influences dynamics. Higher (B50, exhibit enhanced steady rates due increased oxygen availability, while lower (B5–B25) experience stronger events, leading greater secondary formation. global rate follows non-linear trend, peaking decreasing rising again B50 B75. Pre-ignition time increases with content, exhibits an inverse relationship rate. Four distinct mechanisms were identified, producing finer droplets higher forming larger droplets. Puffing evaluated based on occurrences, intensity, effectiveness, revealing peaks B25 in occurrence B10 notable effectiveness. addresses critical research gap droplet-scale WCO fat-derived across wide range blend ratios (B5–B75). findings provide key insights formulations improve fuel spray atomization, ignition stability, efficiency spray-based systems, such as diesel engines, gas turbines, industrial burners, bridging fundamental real-world applications.
