Pinch-off of viscoelastic particulate suspensions
Virgile Thiévenaz, Alban Sauret
Abstract
Using high-speed imaging, the different stages of drop detachment from a capillary are studied for a viscoelastic suspension of spherical particles dispersed in a dilute polymer solution. The dynamics can be rationalized by recognizing the different contributions the particles and polymer make to the properties of the solution and the way these effects influence different time scales of the deformation and breakup process.
