<b>Abstract.</b> This paper deals with the estimation of the thermal conductivity and of the volumetric heat capacity of solids. The experimental setup designed in our previous works consists of a heater symmetrically assembled between two pieces of the specimen with unknown properties. Transient temperature measurements taken in the heated surface of the specimen are used in two estimation procedures, namely: the Levenberg-Marquardt Method and the Sequential Parameter Estimation Technique. Results are presented for the estimation of the properties of Teflon.
<b>Keywords.</b> Thermal Conductivity, Volumetric Heat Capacity, Parameter Estimation, Levenberg-Marquardt, Sequential Parameter Estimation.
