• Tilting of adjacent laser-induced liquid jets

  

  C. F. Brasz, J. H. Yang, and C. B. Arnold, Microfluid. Nanofluid.

A capillary wave excited on the film surface by the first laser pulse explains the tilting of the jet from the second laser pulse, and the effects of time delay and spatial separation between pulses are studied. | Full text | View at publisher

• Dynamics of impulsively actuated jets from thin liquid films

  

  M. S. Brown, C. F. Brasz, Y. Ventikos, and C. B. Arnold, J. Fluid. Mech. (2012) studies the dynamics of fluid ejection in blister-actuated laser-induced forward transfer using computational fluid dynamics. The fluid is forced by a boundary that deforms according to experimental time-resolved images of an expanding blister, and parametric studies reveal the influence of ink density, viscosity, surface tension, film thickness, and blister size on droplet transfer. | Full text | View at publisher
