Abstract : A droplet of a liquid with low viscosity is suddenly exposed to a gaseous jet with high relative velocity. The droplet is destroyed due to both the shear stress and the normal stress exerted by the jet flowing past the droplet. By use of suitable model concepts and simplifying assumptions, solutions are derived for the fluid flow in the vicinity of the symmetry axis of the droplet and in the coupled liquid and gaseous boundary layers at the droplets front face. Deformation and mass loss of the droplet are determined from the liquid flow fields. Finally, a comparison is presented of pertinent experimental data taken from the literature and of numerical evaluations of the theory outlined in this paper. (Author)
