All rights reserved.The thermophysical parameters of a phase change material (PCM) are important for the determination of its performance in thermal energy storage (TES). These parameters include the solid and liquid specific heats (cp,s and cp,l , respectively) and the specific heat of fusion, which is related to the solid–liquid phase change. In addition to the constant values of these parameters, for materials that do not have a clearly-defined phase transition, the enthalpy-temperature curve hT is very useful. An analysis of hT revealed the effective thermal capacity as a function of the temperature cp,eff T . Its constant values at the low and high temperature regions correspond to the cp,s and cp,l values, respectively. In this study, the thermophysical parameters and hT curve of an inorganic PCM CaCl2·6H2O are investigated using a T-history data analysis. The data analysis is performed according to the method reported by Zhang, and its subsequent modification by Hong, while the hT curve is obtained by adopting the method proposed by Marín. The hT curve is fitted using a recent mathematical model for the solidification process including supercooling.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Constant values,Heat of fusion,High temperature,History data,Liquid phase changes,Solidification process,Temperature curves,Thermo-physical parameters[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]CaCl2·6H2O,Erf function,Phase change material,Specific enthalpy-temperature curve,T-history,Thermophysical parameters[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
