This parameter is particularly essential to predict the performance of PCM as latent heat energy storage for certain application since it determines the thermal energy storing capability around its phase change temperature. In this paper, the thermophysical parameters (solid and liquid specific heats and specific heat of fusion) and enthalpy-temperature curve of inorganic PCM of Ca(NO3)2.4H2O and Co(NO3)2.6H2O have been studied by analyzing the temperature vs time data during liquid-solid phase transition (solidification process) based on T-history method. The analysis of the data has been performed following the original method proposed by Zhang et al. and its modification by Hong et al. In addition, the method proposed by Marín et al. have been used to obtain the temperature-dependent enthalpy. We found that the two materials have different phase change behaviors. The obtained thermophysical parameters are then compared with the data from references.[/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]Latent heat energy storage,Liquid-solid phase transition,Phase change temperature,Solidification process,T-history method,Temperature curves,Temperature dependent,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]Ca(NO3)2·4H2O,Co(NO3)2·6H2O,enthalpy-temperature curve,Phase Change Material (PCM),T-history method[/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]https://doi.org/10.1088/1742-6596/1204/1/012057[/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]
