| Abstract: | A new experimental method for measurement of the thermal conductivity of material at solid and liquid phases near the melting/freezing point has been designed.The thermal conductivity of pure metal,alloy,organism as well as the packed bed composed of distilled water and sodium glass which have been obtained by this method at low temperature phase point are good agreement with datas from the literatures as well as from the mathematical simulation.The results prove the method on research heat conduction and thermophysical property at phase transition point is feasible. |
