Measurement of thermal conductivity and thermal resistance with a tiny hot plate
Yves Jannot, Benjamin Remy and Alain Degiovanni
A new thermal conductivity and thermal resistance measurement method is presented. This stationary method is dedicated to heterogeneous materials and systems to which transient measurement methods cannot be applied. The experimental device is detailed and an exact heat transfer model based on integral transforms is developed. The estimation method both with the uncertainty evaluation process is presented. Experimental results obtained with materials which thermal conductivities are known validate the method. An application to the measurement of the thermal resistance of a heterogeneous material (double glazing insert) is presented.
Keywords: Measurement technique, thermal conductivity, stationary hot plate, quadrupolar model.
