Abstract
This paper presents the effect of convection flow on melting behavior of a water-insoluble material immersed in water. A rectangular n-hexadecane block as a water-insoluble material is placed vertically in the water. Then the shape of the melting block and its melting rate are recorded via photography. The velocity of the water in the test vessel is measured by using PIV. The local heat transfer coefficient of the block is defined based on the melting rate. From the result of this experiment, it is found that the local heat transfer coefficient increases as time elapses, because the effect of hindering melting of the melting liquid flow along the block gets weaker.
