     the thermal performance and energy storage capabilities of a 54 °c organic paraffin wax is be tested and directly compared using three common different thermal conductivity enhancement methods (tce). these include the use of graphite foam with infiltrated pcm, aluminum foam with infiltrated pcm, and pcm with 10 wt% graphite nanofibers. the applied heat flux varies from 1.93 w/cm2 to 19.3 w/cm2. this allows the study of higher heat flux conditions than any previously studied and the first direct comparison of the effectiveness of these three different methods on the control of the heated base temperature. the performance of the pcm in both the solid and liquid phase as well as the motion of the melt front between the two phases is examined for each tce configuration.
