Capillary breakup of free and wetting liquid bridges of aqueous xanthan gum solutions
This study experimentally investigates the capillary breakup of aqueous xanthan gum liquid bridges, revealing that while free bridges exhibit distinct inertia-capillary, elasto-capillary, and viscous-capillary regimes, wetting bridges display a unified viscous-capillary response that collapses onto a master curve due to flow history effects and shows reduced sensitivity to substrate wettability.
