Abstract

Jetting mass and droplet morphology variations in a high-viscosity power-law fluid dispensing system were investigated. A specialized dispensing system, containing a piezoelectric actuator, displacement amplifier, and needle-valve nozzle, was developed for high-viscosity fluids. Hydrogels served as non-Newtonian fluids, and a power-law model was employed to analyze the viscosity up to a shear rate of 1,000 (1/s). The needle, driven by a trapezoidal signal, acted as a piston, and changes in the jetted droplet mass and length were measured by varying the needle displacement and frequency. The experimental results well-matched the predicted ones (error: 10%). The needle movement generated Couette–Poiseuille flow, which increased the fluid shear rate and induced shear-thinning, in the dispensing chamber, thereby reducing the viscosity. A large number of droplets with similar masses (within 5%) and lengths were obtained at high driving stokes and frequencies. This analytical model is suitable for designing precise droplet-dispensing systems.
