✦ Synopsis

The numerical simulation of a droplet deformation and solidification on a cold substrate was performed with SMAC algorithm. The substrate temperature histories and the degree of deformation were measured by use of a droplet of n-eicosane and n-cetane. The numerical results showed good agreement with the measured ones. The solidification of a droplet on a substrate occurs immediately after the deformation. A simple model to estimate the deformation and the solidification time was also proposed. Both the normalized deformation and solidification time are proportional to the 0.2 power of the Reynolds number. The solidification time is two orders of magnitude higher than the deformation time.

## Abstract In microfluidic devices the fluid can be manipulated either as continuous streams or droplets. The latter is particularly attractive as individual droplets can not only move but also split and fuse, thus offering great flexibility for applications such as laboratory‐on‐a‐chip. We consid

Simultaneous spreading and infiltration of inkjet-printed droplets has been studied. Small (54- and 63-microm diameter) droplets of an aqueous polymer solution (2.4 vol% polyacrylic acid, PAA, MW 60,000) were deposited on high green density porous ceramic beds, and the wetting-induced spreading and
