The Transient Plane Source method (TPS) simultaneously measures thermal conductivity and thermal diffusivity. This paper investigates the possibilities of using sensors, to record the thermal effusivity of a substrate. With the original method, the thermal effusivity of uniaxial, homogeneous materials in the through-plane direction can ...
Transient methods are often preferred to steady-state methods when testing the thermophysical properties of materials because of they are simple to use, can quickly produce measurements, and can simultaneously test three thermal properties. There are two factors that influence the accuracy of contact transient testing ...
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) ...
Using the dynamic plane source (DPS) technique, the thermal properties of highly and lowly thermally conducting materials were measured. The theory behind the technique is explained, and three well known materials are analyzed and the accuracy of the method is found to be within 5% of ...
