GRAVITY SEDIMENTATION-INDUCED DEFORMATION OF A DROPLET UNDER CONDITIONS OF BLOWING-OVER BY AN INCOMING AIR STREAM

The results are presented of experimental investigation of the loss of the viscous droplet shape stability in the course of gravity sedimentation of droplet under conditions of blowing-over by an incoming stream at low Weber numbers (We < 7). A new scheme of a setup for studying the droplet deformation by aerodynamic forces is suggested, with the aid of which a qualitative picture of droplet deformation and an empirical dependence of the degree of deformation on the Weber number have been obtained in the range of Reynolds numbers Re = 490–2070.
