Abstract

There is a lack of knowledge on the growth dynamics of the formation of a new ice lens without frozen fringe in freezing colloidal suspensions. With experimental observations, we revealed that a new ice lens can be induced by a single ice spear rather than frozen fringe. This ice spear is possibly from the particle-induced undercooled region in front of the freezing interface and the consequent morphological instability. After the appearance of the new ice lens, its growth dynamics are quantitatively analyzed. The growth speed of ice decreases with time, which can be attributed to the premelted film flow-controlled interface movement.
