Agarwala, S.Prabhu, K.N.2026-02-052020Thermochimica Acta, 2020, 685, , pp. -406031https://doi.org/10.1016/j.tca.2020.178540https://idr.nitk.ac.in/handle/123456789/24020A new method based on solution to inverse heat conduction problem for the assessment of solidification parameters of PCM salts has been proposed. The method estimates the mold -salt interfacial heat flux and it is used to calculate the latent heat of salt PCMs using calorimetry based energy balance equations. This method is more accurate compared to Computer Aided Cooling Curve Analysis (CACCA) techniques as it eliminates the drawbacks involved with base line fitting calculations and errors introduced due to the improper selection of solidification points. Pure salt PCMs such as KNO<inf>3</inf> and solar salt were used for the validation of this technique. Both air and furnace cooling were adopted to demonstrate the effect of cooling rate on solidification characteristics. The wettability of salt samples on mild steel surface was analyzed to account for the difference in the thermal behavior of salts. © 2020 Elsevier B.V.Computer aided analysisCoolingCurve fittingEnergy balanceHeat fluxHeat storageInverse problemsPhase change materialsPhase diagramsPotashPotassium NitrateSaltsSolidificationThermal energyComputer-aided cooling curve analysisEnergy balance equationsExperimental approachesInverse heat conductionInverse heat conduction problemSolidification characteristicsSolidification parameterThermal characterizationHeat conduction
