Type of article: Article, IJR article

Summary

Experimental and analytical studies for freezing phenomena of ethylene glycol solution around a vertical cooled polyvinyl-chloride cylinder have been performed. It is found that the crystal ice formed around the vertical cylinder is removed from the cylinder surface due to a buoyancy force acting on the crystal ice. The crystal ice slides along the cylinder surface due to buoyancy force and grows in the shape of a tube by joining with the neighboring ice. It is shown that the onset of ice removal condition is related to the heat flux ratio, `from the cylinder surface into the cylinder' to `from the cylinder surface into the solution'. The ice removal occurs more easily for short cylinders than for long ones.
