A Numerical Study of Liquid Bridge Solidification

Solidification of liquid bridges appears in a vast number of applications. To better understand this process, we numerically study the solidification process of a vertical liquid bridge. The bridge is stuck to two disks (or rods) of the same size. The solidification starts from the stable shape of the bridge. We found that the upper and lower liquid–solid interfaces propagate with almost the same rate, and a ring (or protrusion) is created around the bridge when the bridge finishes its solidification.
