Using a sensitivity analysis, we find that varying contact resistances and cell resistances contribute strongly to temperature differences between cells, from which we define safety thresholds on cell-to-cell variability. . The design of the thermal energy storage (TES) modules rely on the thermal conduction path between the two fluid circuits. Thus, the thermal conduction of the graphite foam along with the contact conductance between the copper tubes and the composite material are critical factors in the performance. . In this paper we consider the problem of dynamic performance evaluation for sensible thermal energy storage (TES), with a specific focus on hot water storage tanks. ANSYS FLUENT simulations, validated by experiments, analyze the impact of pipe geometry, HTF inlet temperature, and flow ra e on thermal efficiency and entropy generation, keeping PCM volume constant. Results show lower. . Experiments were conducted on stainless steel encapsulations without fins and stainless steel encapsulations with solid internal fins for the mass flow rates of 2, 4, and 6 L/min with a heating source of constant temperature bath. Water and paraffin wax was used as the heat transfer fluid and phase. .
