Abstract: This study developed a model that used a transient plane source (TPS) sensor to measure the specific heat capacity of anisotropic materials. The underside of a sample holder with a diameter of 20 mm, and a height of 5 mm was attached to a Kapton TPS sensor. During measurements, the sample holder was hung inside a steel tube at atmospheric pressure. Results showed that the model underestimated the heat capacity, which suggests that heat convection cannot be neglected in the calculations, as previously thought. The two- and three-lump models generated good results that were in agreement with the calculated values. The TPS method to should be used to measure heat capacity more extensively in the future, considering this study mainly focused on silver samples.
