Inverse method to describe crystallization of undercooled water in cold storage tank

The objective of this work is to a physical model describe the thermal performance cylindrical tank filled with spherical water capsules during storage period. A particularity encountered in type storage; it refers supercooling phenomenon caused by delay crystallization capsules. originality consists evaluating heat flux exchanged between transfer fluid (HTF) and using experimental data (here, temperature) an inverse method. method addressed genetic algorithm (GA). determined for one case flowrate condition has been applied other flowrates evaluate temperature HTF at outlet obtained results are then compared from literature. good agreement was found numerical results. influence on shape released period also analysed discussed.
