title: Faceted ice growth in hydrophilic and hydrophobic channels.
abstract: This study is motivated by the cryo-preservation for tissues, which is related to the solidification of blood in a confined space. The morphological behavior of growing ice facet in 1.3 mm hydrophilic and hydrophobic channels is the focus of this study. Both DI water and KCl solution were solidified without seeds in the channels and the growing front facet was discussed in regards to contact angle, in-situ morphology, conductivity difference between two phases and solute segregation. For DI water, the formation of facets was observed during ice growth in both hydrophilic and hydrophobic channels and could be classified into two modes according to the local curvature of the interface. The facet was formed at different positions of the interface in hydrophilic and hydrophobic channels. Solutal segregation effect was taken into consideration to partially govern the interface morphology and the facet formation during solidification of the KCl solution. In addition, the growth rates of the ice growth with a facet were also compared and discussed.
