Many investigations on the utilization of finned tubes have been performed to enhance heat transfer in a latent heat thermal energy storage (LHTES) systems. Detailed information on the heat transfer for the solidification process in the LHTES having tubes with longitudinal fins has been obtained experimentally and theoretically. For LHTES systems having tubes with radial fins, however, no thoretical studies to obtain the overall heat-exchanger performance appear to have been reported since usual numerical methods (e. g. a finite difference method) cannot be easily applied to the problem. In the present study, the overall performance of a LHTES system having tubes with radial fins has been obtained using a new method which the author proposed recently, and the performance has been compared with those of LHTES systems having a tube with longitudinal fins and having an unfinned tube.
