In this study the interaction of diesel sprays with thin oil films is optically investigated under engine relevant conditions. Oil films of a few micrometer thickness are generated using a novel high-pressure spin coater. The behavior of spray impingement on a dry and a wetted wall is compared using high-speed visualizations, interferometry and Phase Doppler Anemometry. On this basis, the influence of film presence before interaction on macroscopic spray properties, droplet diameters, droplet velocities and film thickness after interaction is studied.
