Production and Analytical Comparison of Atomization Characteristics for Ternary Blends of Biodiesel
TL;DR: In this article, the ternary biodiesel blends with diesel fuel produce almost equal drop size when compared with some binary blends with large quantities of diesel, and the sauter mean diameter of atomization is also computed by analytically.
Abstract: By the plenty usage of diesel fuel in automobiles, it is necessary to switch over to the alternate fuel such as biodiesel. Generally non edible oils are blended with diesel after the esterification process. But here ternary biodiesel blends with diesel fuel produce almost equal drop size when compared with some binary blends with large quantities of diesel. The ternary biodiesel blends give less amount exhaust emission than the binary blends with diesel. In this work, biodiesel is produced from linseed and rubber seed oil by trans-esterification process and then the fuel atomization characteristics have been determined, The sauter mean diameter of atomization is also computed by analytically. The ternary blends having 90% diesel and 5% linseed biodiesel, 5% rubber seed biodiesel and also 80% diesel, 10% linseed biodiesel and 10% rubber seed biodiesel are observed to give comparatively similar atomization characteristics of diesel.

TL;DR: In this article, a pressure swirl atomizer was used to create a swirling motion imparted to the fuel, leading it under the action of centrifugal force and spreading the fuel in hollow cone after the fuel leaves the orifice.
Abstract: The type of fuel atomizer chosen for this study is the pressure swirl atomizer. This type of atomizer can create a swirling motion imparted to the fuel, leading it under the action of centrifugal force and spreading the fuel in hollow cone after the fuel leaves the orifice. The reason for choosing this type of injector is because it was widely used in gas turbine and liquid propellant rocket. The fuel to be tested is the blends of palm kernel biokerosene and Jet A1 meet some specifications selected for study of the ASTM D1655 standard. The injector was simulated using CFD simulation software, Fluent to predict the behavior of an evaporating fuel spray and also the angle of spray. The Sauter Mean Diameter (SMD) and the spray cone angle are evaluated and compared with the empirical equation result. Besides that the SMD also measured with a laser scattering system to compare with the theoretically method result.
