Paper Abstract

Optical scattering by fuel droplets of spray jets can provide information about droplet evaporation in a combustion chamber. Evaporating fuel droplets are often spatially inhomogeneous and non-spherical. Spatial inhomogeneities in droplets can occur in the imaginary or in the real part of the index of refraction. We review some of the theoretical progress to date in modeling scattering by non-spheres and by inhomogeneous droplets. These models help investigate the effects of shape and refractive index perturbations on morphology dependent resonances of droplets. These investigations may lead to the use of such effects as tools for droplet diagnostics.
