A typical culinary setting involves liquid condiments with different constitutive behaviors stored in jars, bottles, pitchers, or spouts. In the dynamic kitchen environment, handling these might require pouring, drizzling, squeezing, tapping, demonstrating interplay of container geometry, fluid properties, and expertise. There is, course, occasional accidental toppling. We investigate combined effects surface confinement dimensions on short-time spilling pouring dynamics a toppled cuvette. While attesting to fact that smaller cuvettes (which can be termed as capillaries well) do not spontaneously spill, larger exhibit are dependent property, viscosity, flow rheology. For Newtonian liquids, it is observed determined largely by coupling viscous gravity forces inducing non-intuitive behavior at higher conduit dimensions. The inclusion rheology for non-Newtonian liquids soup makes only an properties but also function meniscus retraction demarcating “splatter” three regimes “not spilling,” “on verge “spontaneous spilling.” delineate interactions leading motion provide mapping whether would spill if momentarily then immediately returned upright position. This study aids understanding fascinating physics could lead new kitchen, biomedical, industrial technologies.

The evolution characteristics of a low-velocity dispersed phase into continuous shear flow have numerous applications across biomedical devices, chemical processes, water management in fuel cells, spray systems, film deposition, and atomizing devices. arise from complex interplay wettability, hydrodynamics, interfacial properties, which, when constrained by confined geometries such as those present fascinating multiphase-multiphysics problem. This study investigates the impact signature geometry velocity ratio between phases on phase. footprint shape generated droplet guide pressure distribution, deformation, subsequent cross-flow-induced stretching. By systematically analyzing dynamic effects capillarity, inertia, air-shear, gravity, viscosity, confinement, we classify fate liquid within classical regimes: jetting, threading, dripping. These distinct regimes are mapped using non-dimensional numbers, quasi-universal characteristic is obtained relative to ratios. findings this research contribute precise control prediction dispersed-phase which play pivotal role enhancing efficiency generation harvesting deposition techniques, coatings, point-of-care diagnostic work underscores relevance integrating experimental computational insights for optimizing interface-driven processes interdisciplinary applications.
