A note on the article titled: Experimental and numerical investigation of solid particles thermal energy storage unit, by: A. Benmansour, M.A. Hamdan, A. Bengeuddach, published in Applied Thermal Engineering, 26, 513-518 (2006)

Abstract

Maryam Moradi, Amir Rahimi, and Mohammad Sadegh Hatamipour from Department of Chemical Engineering, Faculty of Engineering, University of Isfahan, Iran, critically analyze an article titled 'Experimental and numerical investigation of solid particles thermal energy storage unit' by A. Benmansour, M.A. Hamdan, and A. Bengeuddach. Similar boundary and initial conditions are used for comparison of the two referred models. Both of the models have been developed with the assumption that when the temperature of PCM reaches to its melting point, the phase change period begins and the PCM temperature during this period remains constant. After this process is finished and all of the solid paraffin wax melted the temperature begins to rise. In the next section the results of the present model are presented and compared with the results of Benmansour and colleagues, model and also with corresponding experimental data. Unfortunately, the mathematical model results which were reported by Benmansour are not in agreement with this theory.
