摘要

A water ethanol mixture can exist either as a liquid or solid phase. Because of this property, waterrnethanol mixtures are becoming considerably important as an environment friendly coolant or arnthermal storage material. The crystallization in the mixture occurs in two ways: firstly, equiaxedrncrystals grow in the mixture and secondly, crystal growth occurs within the mushy layer, which isrnformed on a refrigerated surface. Here, in order to understand the characteristics of the crystalrngrowth within the mushy layer, the effect of surface temperature on the crystal growth was investigatedrnby varying the concentrations of ethanol and observing the crystal growth in a liquid pool inrncontact with a refrigerated surface. Five types of mushy layers were observed in the solid-liquidrncoexisting region of the water ethanol mixture, and further, three types of crystal growth processrnwere indentified: namely, the formation of a dendric layer, a white layer and a transparent layer atrnvarious surface temperatures and concentrations of ethanol. Additionally, it was found that mushyrnlayer thickness grew in proportion to the 1/2 power of time in the early stages of crystal growth, forrnlow ethanol concentrations.
