Crystal ice formation of solution and its removal phenomena on inclined cooled plate

Abstract

Experimental studies for freezing phenomena of ethylene glycol solution on an inclined polyvinyl-chloride plate have been performed. It is found that the crystal ice formed on the inclined cooled plate is removed from the plate surface due to a buoyancy force acting on the crystal ice. It is shown that the crystal ice grows in a shape of sheet by joining with neighboring ice and that the ice slides along the inclined surface when it is removed. The onset of the ice removal condition is related to the cooling heat flux at the surface. The ice removal occurs more easily for the plate of large inclination than that of a small one.
