Solidification of Pcm at Low Temperature in a Cylindrical Vessel

Abstract

The outcome of this study is to provides the data for experimental analysis of solidification of phase change material (PCM) in a cylindrical vessel. Water in pure condition  was considered as a PCM, copper was identified  for the cylindrical vessel and liquid nitrogen  took the role of cooling fluid. The experiments carried out  for dissimilar sizes of cylindrical cavities, whose dimensions were 25×25, 25×35, 40×40, 30×40 and 50×50 (diameter in mm× height in mm). At first the PCM was noted down at room temperature for all cavities. The temperature variation is presented at various time steps throughout the solidification of PCM. The result indicates the convection from the atmosphere has a notable effect on the upper surface. As the  cavity’s diameter changes, for the same height, then notable change in solidification time is observed when  height is changed, without changing internal diameter, the change in solidification time is less significant.
