Development of biofuel is widely used among industrial sectors due to costly and environmental issues caused by petroleum diesel. Biodiesel-diesel fuel blend is thus implemented to substitute the current fossil fuel used in power plant. The aim of this research is to verify and validate the simulation numerical results of atomization characteristics of biodiesel-diesel fuel blends with the experimental results. Computational Fluid Dynamics (CFD) is used to predict and visualize the spray characteristics of biodiesel fuel blends in the fuel atomizer. Various percentage biodiesel and diesel fuel blends such as pure diesel, B20, B50, B80 and B100 have been simulated using CFD software according to their physical properties (density, viscosity and surface tension) to obtain Sauter mean diameter (SMD), spray cone angle and spray pattern of each fuel blend. Simulation results show that SMD increases and spray cone angle decreases as the percentage of biodiesel increases in the blend. The percentage deviation between theoretical and simulation SMD is as high as 2%, approximately. As for spray cone angle, the percentage deviation between experimental and simulation result is as high as 26%, approximately
