Abstract
A relative velocity correction model (RVC), combined with the drop tracing system and spherical coordinate transformation, was developed and implemented in KIVA-3V code to yield grid-independent results for the spray simulations, especially for 3-D cases. The model applies the theory of steady turbulent jet flow to obtain sectional distribution of the gas-phase velocity along the spray axial in near region, which is used to correct the relative velocity between the drop and gas phases.
The computed results were compared with the experimental data for both single-hole and three-hole fuel injections, including the spray tip penetrations and the spray images. The comparison shows that the RVC model performed well for all the cases.
