High-pressure spray assessment

The aim of this study was to assess Lagrangian-Eulerian CFD models for the simulation of Gasoline sprays under non-flashing and flashing conditions.

Plot of the spray penetration over time for flashing and non-flashing spray.

Non-flashing (upper) and flashing (lower) sprays evolutions shown by mixture fraction iso-surfaces coloured by flow field velocity.
