A similarity curve proposed by Shamsundar was examined as to whether or not it is an appropriate chart to clarify the configuration effect on the thermal performance of a latent heat energy storage unit. The unit consisting of concentric circular tubes with longitudinal fins in the annular space was analyzed numerically for the solidification process by means of the ADI method. A similarity rule was found to be valid in application to this unit as well as to an unfinned unit, while it suffered somewhat with increasing number of fins. The differences among similarity curves for the different numbers of fins were so remarkable that the configuration effect was able to be discussed according to this chart. Heat exchanger effectiveness evaluated from the similarity curve was compared with existing experimental data and shown to be in good agreement within a sufficient degree of accuracy.
