Grahic Jump Location
Soot mass fraction distribution in the plane of the spray axis as predicted by the KH and the KH-RT models at 3 deg BTDC. The spray profile has been superimposed for reference.
Grahic Jump Location
Predicted (dashed line) and measured (solid line) cylinder pressure and spray tip penetration for the range of operating conditions studied by Espey and Dec 4. Predictions are for the KH-RT model. For the spray tip penetration, the measured values are shown by the solid squares, the penetration of the farthest droplet is in the solid line and the penetration of 90 percent of the liquid mass is shown by the dashed line.
