“…Another detachment event described in the literature is detachment as a result of strong air currents or high liquid velocities, the so-called air-blast atomization. 20,21 Roisman et al investigated and modeled a spray impact on a liquid film under strong air flow. They were able to describe the detachment of droplets from the liquid film due to the air flow using the dimensionless Weber number of the air flow We G .…”

“…The interaction of droplets on surfaces and fluid films are well described in the literature. [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] The droplet impact and rebound as well as the surface wetting of dry walls is described from Richter. 6 The interaction between a droplet and a fluid film is highly influenced by the droplet size to film thickness ratio.…”

Since the technology of direct injected engines has become more and more prevalent, combustion anomalies such as pre-ignition events have been occurring with increasing frequency. The interaction between the fuel-spray and the oil wetted cylinder liner is considered to be a partial cause for these phenomena. The incoming fuel jet can lead to a detachment of secondary droplets, which may affect pre-ignition events due to their changed flammability properties. To characterize these secondary droplets, spatially and temporally highly resolved optical investigations on the fuel-oil-film-interaction are carried out in this work. Using laser induced fluorescence and two high-speed cameras both fluids are optically separated. Thereby the secondary droplets can be detected and characterized in size, velocity vector, and composition.
