The present work experimentally studies the breakup of single viscoelastic droplets subject
to shock-induced gas flow. Millimeter-sized droplets, made from aqueous solutions of
carbonxymethylcellulose and polyacrylamideare, are examined. Both non-Newtonian
liquids share similar shear viscosities while the latter shows a stronger elasticity. The
droplets are ejected discretely into a shock tube inside which shock waves of varying
strength are generated to achieve different Weber numbers. The drop...»
