The authors present a method for measuring the thermal conductivity and thermal capacity of thin insulating and super-insulating materials. The new method is compared to previously existing methods and elaborates upon why these methods are unacceptable for the measurement of thin insulating materials. The researchers developed a 3D and 1D model in order to aid in the determination of thermal conductivity. The proposed method involved sandwiching a sensor/heater between ...
Outlines the problems with measuring the thermal conductivity of low-density insulating materials and addresses this by proposing a three layer method for the accurate measurement of thermal conductivity. This method involves a sample being placed between two conducting brass plates (one heated via hot plate) and monitoring the temperatures of these two plates as the experiment progresses. Mathematical equations are derived in order to make an accurate model for thermal ...
This paper studied in-depth the transient hot plate method, by comparing this method to others in order to develop a short test time in which thermal effusivity and thermal conductivity can be measured simultaneously. To investigate this proposed model, four metal samples were analyzed using various techniques to ensure the accuracy between methods. To encompass a wide thermal conductive range, the thermal conductivities of the four metal samples tested, ranged ...
