Abstract: This article studied the potential thermal conductivity deviation of anisotropic materials using a numerical simulation. Anisotropic thermal conductivity may experience deviation due to its noncompliance of the theoretical assumption of the transient plane source (TPS) method. The TPS method was used to measure the in-plane and through-plane thermal conductivities of anisotropic materials where the volumetric heat capacity was known. It was found that the TPS method could be used to measure the in-plane and through-plane thermal conductivities of anisotropic materials precisely if the thickness of the sensors that are being used are neglected.
