DoS RHEOMETRY
Capillary-driven thinning & pinch-off dynamics of complex fluids
Elastocapillarity. Finite-time Singularity. Self-Similarity. Printability. Jettability. Sprayability
Inertio-capillary, viscocapillary, elastocapillary, power law and terminal viscoelastocapillary thinning.
Influence of material properties and microstructure on fluid neck shape and shape evolution.
We introduced Dripping-Onto-Substrate (DoS) rheometry for characterizing capillarity-driven pinching dynamics and extensional rheology response of complex fluids. (Dinic et al., ACS MaroLett. 2015; Lab Chip, 2017)
Ongoing and recent work aims to connect heuristic quantities like jettability, sprayability, printability, spinnability, stickiness, stringiness, gloppiness, and ropiness to polymer physics, pinching dynamics, and non-Newtonian fluid mechanics.
