[IJ4.1-02] Droplet Deposition Simulation with the Consideration of Evaporation and Viscosity Change 2

*Masami Kadonaga1 (1. RICOH COMPANY, LTD.)

Numerical simulation model of free surface, with the consideration of water evaporation and viscosity change, is proposed in order to investigate a droplet deposition problem. The model includes moisture convection - diffusion analysis, estimation of viscosity change due to the moisture change. The behavior of droplet deposition on printing media is simulated, and the thickening on the surface of the droplet is reproduced. Behaviors of a sessile droplet and two droplets on a media are simulated with the consideration of evaporation and viscosity change, and the calculations show good agreement with the experimental observations.
