A method of stimultaneous estimation of the moisture diffusivity together with the other thermophysical properties of a drying body as well as the heat and mass transfer coefficients by using only temperature measurements, has been analyzed in this paper.The Levenberg-Marquardt and the hybrid optimization method were applied for evaluation of the unknown parameters. The two moisture diffusivity parameters and the heat capacity of the drying body together with the heat and mass transfer coefficients were simultaneously estimated. The obtained results show good agreement between the evaluated and exact values of parameters and confirm the validity of the proposed method. An analysis of the influence of the temperature measurements errors on the accuracy of the estimated parameters was also presented.
