“…e method consists of discretising a region of space by creating a spatial grid, by dividing a region of space into small control volumes. It is solved in each of them, and the discretised conservation equations are then solved in each so that in effect, an algebraic matrix is an algebraic matrix in each cell iteratively until the residual is sufficiently small [5].…”

“…e evaluation of the mean mass requires a formula already developed by Wigg (1959), who analyzed the mechanism of atomisation with air jets, emphasising the importance of the kinetic energy of the atomising air, and indicated that the energy difference between the air jet in the inlet and the emerging spray is a dominant factor affecting the mean droplet diameter. In 1964, using experimental data from other researchers on the atomisation of viscous liquids and air in Y-type injectors, Wigg succeeded in deriving a dimensionless expression which allows to evaluate the mass median diameter of the spray droplets [5]:…”

Hydrocarbon injection is an important stage in combustion, where the atomisation process is involved the atomisation process which consists of disintegrating the fuel into small droplets, through an injector to add more transfer area, the fuel, through an injector to add more transfer area. The size of droplet size generated by the injector must be less than 80 μm to ensure good combustion and avoid combustion and avoid pollutants such as CO and NOx. This research worked with ethanol, a low-emission hydrocarbon, which has a high viscosity which makes it difficult to achieve the correct droplet diameter. This type of study needs to be both theoretical and experimental with simulation being a great tool to replace the latter. The finite element method included in the Flow Simulation package of the SolidWorks software was used in this research. The Flow Simulation package of the SolidWorks software was used, where a Y-type injector was sketched to be evaluated. The dynamic simulation helped to measure the velocity field, at the outlet of the air nozzle, a cavity with a diameter of 0.4 mm, which helps to increase the kinetic energy of the air. The kinetic energy of the fluid obtains the highest values of the Mach number in this area.
