Ice formation phenomena as well as freeze-shut conditions of flowing water in an isothermally cooled parallel plate channel are examined. An ethylene glycol 4.6 wt% solution is also used as a test fluid to compare with the results of water. It is found that the ice formed in the solution flow is different from that in water flow in thermal properties, and that the mushy ice formed in the solution at the expanded flow regions affects significantly the freeze-shut conditions. The present analytical results for freeze-shut conditions of water as well as solution flows agree with the experimental data, and show that an ethylene glycol 4.6 wt% solution is a little harder than water to make the flow freeze shut.
