Abstract

In this work two-photon laser-induced fluorescence (2p-LIF) laser sheet imaging is used to analyze the structure and the atomization behavior of water and ethanol sprays. Multiple light scattering is reduced by 2p-LIF measurements using a femtosecond laser. This allows high-contrast spray imaging close to the nozzle resulting in an improved identification of single liquid structures. A commercial 6-hole DISI (Direct-Injection Spark-Ignition) injector was studied at different injection pressures, operated with ethanol and water containing a LIF dye (fluorescein). Compared to water, the ethanol spray structure shows increased cone angles in the nozzle near-filed. For the size of the liquid structures, no clear dependency on the fluid properties is observed in this spray region.
