Abstract
The measurement of the intrinsic diffusivity of a semitransparent sample is investigated by means of the flash method. A precise analytical model of the combined transient conductive and radiative transfer (quadrupole formulation) is used for the parameter estimation problem. Maps of sensitivity maxima and standard deviations on the parameters are plotted in order to determine whether it is possible to identify the parameters, especially the diffusivity. The presented results show the case of black boundaries as it emphasises the radiative transfer and are then compared with the case of the classical gold boundaries method
