Abstract:
Structured Laser Illumination Planar Imaging (SLIPI) is used in combination with LIF/Mie ratio and two-side Mie imaging (dual-SLIPI) for a two-dimensional mapping of both the droplet Sauter Mean Diameter (SMD) and the extinction coefficient ( ). By means of combining the two techniques simultaneously, the local distribution of droplet concentration as well as the liquid volume fraction can also be deduced. This approach is for the first time tested for the characterization of a steady hollow-cone water spray.
