Experimental research on a method for phase change material thermal conductivity

Thermal conductivity is one of the important thermal characteristic parameters for phase change material(PCM).At present,most of PCM thermal conductivity is measured under the ideal state which is greatly different from the actual state.In the paper,a thermal coefficient measuring device is used for measuring the thermal conductivity of paraffin wax in hot air circulation state.The result shows that although there is deviation compared with ideal state value,the thermal conductivity measurement can satisfy the requirement of engineering design.
