This paper presents an experimental study of heat transfer during latent heat storage cycle (charging/discharging) in a vertical cylindrical system. The experimental setup consists of two cylindrical tanks filled respectively with hot and cold water, a test bench, and measurement instruments. The test bench, thermally insulated with glass wool, is also composed of two vertical concentric tubes whose annular space contains the paraffin wax as a phase change material (PCM). The heat transfer fluid (HTF) flows in the upward direction of the inner tube (HTF pipe). The storage capacity of the paraffin wax characterized by a melting temperature of 56°C could be quantified. During one cycle of thermal storage (charging/discharging), the instantaneous temperature variation at the specific location will be done. Also, the influence of heat transfer fluid (HTF) mass flow rate on the time average temperature along the radial direction is examined.
