“…It was suggested by most researchers that the physical properties of liquid fuel were the intrinsic factors affecting its spray characteristics [9][10][11][12][13]. Boggavarapu et al [9] reviewed the effect of fuel properties on the atomization process for both biofuels and fossil fuels and summarized that biodiesel sprays showed faster penetration and narrower spray plume angles and larger droplet sizes as compared to diesel.…”

“…Boggavarapu et al [9] reviewed the effect of fuel properties on the atomization process for both biofuels and fossil fuels and summarized that biodiesel sprays showed faster penetration and narrower spray plume angles and larger droplet sizes as compared to diesel. Battistoni et al [10] investigated spray simulation results, indicating that among the properties affecting the spray characteristics, density and viscosity played the most important roles. Diesel fuel provided a significantly higher penetration and lower cone-angle compared with biodiesel in a convergent conical nozzle.…”

Abstract:The objective of this study was to investigate the macroscopic spray characteristics of different 0%-100% blends of biodiesel derived from drainage oil and diesel (BD0, BD20, BD50, BD80, BD100), such as spray tip penetration, average tip velocity at penetration, spray angle, average spray angle, spray evolution process, spray area and spray volume under different injection pressures (60, 70, 80, 90, 100 MPa) and ambient pressures (0.1, 0.3, 0.5, 0.7, 0.9 MPa) using a common rail system equipped with a constant volume chamber. The characteristic data was extracted from spray images grabbed by a high speed visualization system. The results showed that the ambient pressure and injection pressure had significant effects on the spray characteristics. As the ambient pressure increased, the spray angle increased, while the spray tip penetration and the peak of average tip velocity decreased. As the injection pressure increased, the spray tip penetration, spray angle, spray area and spray volume increased. The increasing blend ratio of biodiesel brought about a shorter spray tip penetration and a smaller spray angle compared with those of diesel. This is due to the comparatively higher viscosity and surface tension of biodiesel, which enhanced the friction effect between fuel and the injector nozzle surface and inhibited the breakup of the liquid jet.

The utilization of biodiesel is an effective approach to reduce pollution from internal combustion engines and thus has attracted steadily increasing interest in the recent years. As the viscosity of biodiesel is much higher than that of standard diesel, the atomization characteristics of a biodiesel jet can significantly deviate from those of a standard diesel jet under identical injection conditions. Since atomization of the injected fuel has a strong impact on fuel-air mixing and the following combustion processes, it is important to investigate the atomization of biodiesel and in particular to understand how the fuel properties affect the atomization process and the resulting spray characteristics. In the present study, three-dimensional direct numerical simulations are conducted to investigate atomizing biodiesel and diesel jets. The novel adaptive multiphase solver Basilisk is used for simulations. The statistics of droplets formed in the biodiesel jet is compared to the diesel jet under identical injection conditions.

“…Michele Battistoniet al in his research work compared two different fuels a standard diesel fuel and pure bio-diesel, the methyl ester of soybean oil have been compared with regard to injection pressure. [12]. Jonas Galle et al had focused on failure of the injectors and fuel, when bio diesel was used in engines after working for 50 to 1500 hours failure of injectors were taken place and he tried to improve the operation of the engine at the same time what are the reasons of failure of injectors.…”
