Numerical investigation of the spray-wall interaction was carried out. Wall interaction models that predict the post-impingement state of drops hitting a wall, under internal combustion engines conditions, are still missing. In this paper different existing models were implemented in a modified version of the KIVA3V code. Simulations concerning high pressure sprays in a chamber at different ambient pressures were made. Numerical radial penetrations and spray pattern were compared to experimental data.
