## Abstract A transient shortβhotβwire method has been proposed to simultaneously measure the thermal conductivity and thermal diffusivity of liquids. The method has been applied to the refrigerant HCFCβ22, alternative refrigerants HFCβ32, HFCβ125, HFCβ134a and refrigerant mixtures HFCβ32/125 [35/6
A new method is presented for measuring the low-temperature thermal conductivity of thin electrically-conducting samples. The proposed two-probe technique is useful mainly in the case of non free-standing samples of medium and high thermal resistivity. The method is simple: a resistance bridge is us
