Dynamics of entrained air bubbles inside a piezodriven inkjet printhead
- Entrapped air bubbles in piezo-driven inkjet printing: Their effect on the droplet velocity. de Jong, Jos; Jeurissen, Roger; Borel, Huub; van den Berg, Marc; Wijshoff, Herman; Reinten, Hans; Versluis, Michel; Prosperetti, Andrea; Lohse, Detlef // Physics of Fluids;Dec2006, Vol. 18 Issue 12, p121511
Air bubbles entrapped in the ink channel are a major problem in piezo-driven inkjet printing. They grow by rectified diffusion and eventually counteract the pressure buildup at the nozzle, leading to a breakdown of the jetting process. Experimental results on the droplet velocity udrop as a...
