Summary

As a cooled pipe, polyvinyl chloride has been used. The concentrations of the ethylene-glycol solution are 2, 6, 10 wt%. It is shown that the ice crystal formed in the pipe is removed from the pipe surface and drifts away downstream. It suggests the possibility of liquid-like ice formation by this method. The heat transfer coefficient in the pipe is strongly affected by ice formation and ice removal phenomena; the ice formation rate increases with decreasing Reynolds number. The ice removal phenomenon does not occur for smaller Reynolds numbers and for larger cooling heat fluxes.
