A STUDY ON THE HEAT TRANSFER MECHANISM OF A PHASE CHANGE MATERIAL ALONG THE THREE DIMENSIONAL AXIS OF A SOLAR WAX MELTING CHAMBER

A heat transfer characteristic of paraffin wax by natural convection was studied experimentally. A square wax melting chamber was taken to study the charging/melting characteristics of the PCM. A square wooden block was used to fix the monocouples, which was used to measure the temperature of the pcm radially and axially. DSc was taken for the Paraffin wax used in the study and its thermophysicsal characteristics were studied. Natural convection increases the thermal conductivity of the PCM with time.
