Evolution of Empirical Equations for Prediction of Melting Point and Latent Heat of Alkanes

Abstract

Alkanes and paraffins are well recognized phase change materials (PCMs) for low and medium range temperature thermal energy storage applications. Melting point and latent heat are two crucial parameters for any PCM for its use in any thermal storage application. The values of these parameters are normally measured by expensive and time consuming measuring devices.

In this paper, three empirical equations are presented to predict the melting point and latent heat of alkanes using carbon number as the only input variable. The theoretical results were found comparable with the experimental results within the error limit of ±3.5% for melting point of alkanes with carbon number between 17 and 60. Latent heat values predicted were also in good agreement with the experimental values.
