The author compares some currently existing method of measuring thermal conductivity and elaborates on a couple of newer methods. The pre-existing methods include hot wire and laser flash diffusivity, and the newly introduced methods are the modified how wire (MHW) and transient plane source (TPS) techniques. The necessary conditions (samples sizes, sample composition, test times, etc) are explained for the two newly introduced techniques. Experimental runs are carried out using ...
This paper discusses thermal conductivity measurements on homogenous and non-homogenous materials, using three transient methods: Laser Flash Method (LFM), Modified Hot Wire (MHW), and the Transient Plane Source (TPS). This article also compares the non-destructive nature of the MHW, and the TPS methods, to the destructive nature of the LFM. Research conducted on homogenous materials produced comparable results using all three transient methods. However, when testing non-homogenous materials, such as ...
