Simulation and Modeling of the Spray Characteristics of Biodiesel and Ammonia Mixtures Carbon-Neutral Fuel

Abstract

The purpose of this research is to employ computational fluid dynamics to identify the properties of the spray generated during the spray biodiesel simulation (CFD). The variables under investigation were spray angle, penetration, and area. In the constant volume chamber, biodiesel is used as the fuel for combustion. Different levels of ambient pressure and temperature were used during the simulation. Variable ambient pressure levels of 4 MPa, 6 MPa, and 8 MPa were used. At the same time, the ambient temperature was fixed to 850 K. The results demonstrate that the biodiesel spray angle increased at high ambient pressure. The findings also showed that as ambient temperature rose, the length of the spray and the spray area shrank. Fuel in the constant volume chamber vaporised at a rapid rate as a result of the rise in ambient temperature
