The physics of aerobreakup. IV. Strain-thickening liquids

Abstract

We extend our previous work on aerobreakup of Newtonian and viscoelastic-liquid drops to liquids of dense nanoparticle suspensions with strain-thickening rheology. As in the previous work, the scope includes the full range of aerodynamics, from near-incompressible to supersonic flows, covering all regimes of aerobreakup and employing laser-induced-fluorescence visualizations with μs/μm resolutions. The key physics of Rayleigh-Taylor piercing (1st criticality), Shear-Induced Entrainment (SIE, 2nd criticality), and Kelvin-Helmholtz SIE (3rd criticality) are verified and quantified on the same scaling/theoretical approach as in our previous work but with modifications that account for the rheology of these liquids.
