Case Study

Next, we must measure another quantity which is thermal conductivity, diffusivity or effusivity. Given the “sticky” nature of the material, we avoided the hot wire and hot strip methods, the flash method also seems difficult to implement practically with this type of material. We therefore opt a priori for an asymmetric centered hot plate method with realization of a thin-edged frame to contain the paste under a controlled thickness. We will perform a steady-state measurement to estimate thermal conductivity and then a confirmation measurement in transient regime to estimate thermal effusivity.
