From: Repetitive regime of highly focused liquid microjets for needle-free injection
(a) Rapid bubble expansion and liquid ejection leaves the system in an imbalanced state after the cavitation and the jet creation. (b) The meniscus position tracking in the repetitive regime. The time required to restore the meniscus into its initial position is the minimum delay necessary between two subsequent jets (c) Operational condition for stable jetting. Color of data points reveals their actual value. Isocurves shows the value of required meniscus velocity and are based on the plane fit of data points: \(\dot{Z}(t)=0.0042E+0.71f-1.554\).
