Correction of the enthalpy-temperature curve of phase change materials obtained from the T-History method based on a transient heat conduction model

In this study, a one dimensional numerical transient heat transfer model is used to show that neglecting the insulation thermal mass leads to a systematic error on the obtained enthalpy versus temperature curves. The error is caused by deviations in the transient heat flows for reference and PCM sample when both are cooled down or heated, respectively. These deviations can be corrected by introducing a correction factor.
