Abstract

Transient melting of ice layer placed vertically in the air under condition of natural convection was analyzed and compared with experimental results. First, the heat transfer coefficient on the falling film surface was investigated experimentally, where the natural convection and the vapor condensation of the humid air occur simultaneously. In the data analysis, the Lewis relation was used between the heat transfer coefficient and the mass transfer coefficient. Then, applying the obtained heat transfer coefficient on the falling film surface, the transient melting of ice was calculated. Lastly, a melting experiment was conducted using vertically placed ice layers and ice cylinders. The calculated results agreed well with experimental results.
