Presentation Transcript

  1. Inkjet workshop topics • Drop formation and air entrainment • Collision between free surfaces • Singularities in the shape of the free surface • Instability of a liquid column • Inclusion of air pockets • Fast modeling with lubrication theory • Reproducible deviation of jetting direction • Resonance effects in meniscus • Dirt particles • Contact line movement • Air entrainment ? • What is a sharp edge, transition between wetting and non-wetting • Which factors determine contact line pinning • Evaporation and sedimentation at nozzle edge • Transient effects, harmonic movement

  2. Topics 2 • Drop impact • Splashing, simulation methods • Contact line pinning of an absorbing drop • Sedimentation (coffee stain effect) • Influence of evaporation, crystallization, and polymerization • Coalescence and repelling of drops • Air bubbles • Blocking of filters • Adhesion against porous walls • Nano-bubbles and micro-pancakes with hotmelt ink ?
