Breakup of liquid drops in high speed gas flow.

Masaaki Kawahashi, Hiroyuki Hirahara

Abstract

An experimental study has been performed to investigate the breakup of the droplets by using shock tube in the range of Weber number of 55 to 1500. Breakup process is observed by means of shadowgraph method. Experimental results show that the break-up process could be devided according to their characteristics into two processes, which are the initial deformation process and the disintegration one. The type of initial deformation is unchanged over the range of present Weher number.
