Abstract

This study investigates the impact of ambient pressure and temperature on the spray behaviour of diesel fuel. Spray
simulation tests were conducted using Ansys Forte in a 45-degree sector of a diesel engine under different ambient pressures (1, 4 and 8 bar) and different ambient temperatures (400, 600 and 800 K). Non-reactive conditions were used as they allow calibration of the model for predicting correct spray dynamics. The simulation results of diesel fuel showed that the spray penetration decreased with increased ambient pressure. However, the spray penetration region became longer and wider for diesel fuel because of increased ambient air temperature. With higher ambient temperature the evaporation rate increased.
