“…Higher viscosity and surface tension are mentioned as reasons for the slower break up which causes higher penetration and narrower spray plume angle. In a study on soybean methyl ester, similar conclusions are reported by Park et al [34]. The difference in spray tip penetration is significant after a certain period from the start of injection [31].…”

Ever increasing energy requirements, environmental concerns and energy security needs are strongly influencing engine researchers to consider renewable biofuels as alternatives to fossil fuels. Spray process being important in IC engine combustion, existing literature on various biofuel sprays is reviewed and summarized. Both experimental and computational research findings are reviewed in a detailed manner for compression ignition (CI) engine sprays and briefly for spark ignition (SI) engine sprays. The physics of basic atomization process of sprays from various injectors is included to highlight the most recent research findings followed by discussion highlighting the effect of physico-chemical properties on spray atomization for both biofuels and fossil fuels. Biodiesel sprays are found to penetrate faster and have narrow spray plume angle and larger droplet sizes compared to diesel. Results of analytical and computational models are shown to be useful in shedding light on the actual process of atomization. However, further studies on understanding primary atomization and the effect of fuel properties on primary atomization are required. As far as secondary atomization is concerned, changes in regimes are observed to occur at higher air-jet velocities for biodiesel compared to those of diesel. Evaporating sprays revealed that the liquid length is longer for biodiesel. Pure plant oil sprays with potential use in CI engines may require alternative injector technology due to slower breakup as compared to diesel. Application of ethanol to gasoline engines may be feasible without any modifications to port fuel injection (PFI) engines. More studies are required on the application of alternative fuels to high pressure sprays used in Gasoline Direct Injection (GDI) engines.

“…Mie Scattering is another laser technique that has been used by [23][24][25][26][27] to investigate the characteristics of sprays generated by flash-boiling, pneumatic atomization, slit, piezo-electric, and port fuel injectors respectively. While Laser Induced Fluorescence (LIF) was used to visualize spray atomization [28][29], in addition to the Nd:YAG laser [14,21,[30][31][32][33][34][35][36][37] and other laser techniques mentioned in [12,[38][39][40][41][42][43][44][45][46][47][48]. Shadowgraphs are used as well in spray atomization investigations either individually [49][50][51][52] or accompanied by another optical technique such as laser-based techniques [25,28] and high speed camera [53].…”

Abstract. In the present work, an experimental investigation of spray atomization of different liquids has been carried out. An air-assist atomizer operating at low injection pressures valued (4 and 6 bar) has been used to generate sprays of (diesel fuel, 5, 10, and 15% water-emulsified-diesel), respectively. A Photron-SA4 high speed camera has been used for spray imaging at 2000 fps. 20 time intervals (from 5 to 100 ms with 5 ms time difference) are selected for analysis and comparison. Spray macroscopic characteristics (spray penetration, dispersion, cone angle, axial and dispersion velocities) have been extracted by a proposed technique based on image processing using Matlab, where the maximum and minimum (horizontal and vertical) boundaries of the spray are detected, from which the macroscopic spray characteristics are evaluated. The maximum error of this technique is (1.5% for diesel spray) and a little bit higher for its emulsions.
