Abstract:
Results of an experimental study of two regimes of stripping breakup of low-viscosity liquid drops in the flow behind the shock wave in the range of Weber numbers from 200 to 8000 are reported. A phenomenological pattern of drop breakup is constructed on the basis of data on drop deformation and on the flow around the drop. A physical criterion of the change in stripping mechanisms of drop breakup is formulated.
Keywords:shock waves, gas-drop mixtures, aerodynamic breakup of drops.
