L. Vozar et T. Sramkova, 2 DATA REDUCTION METHODS FOR EVALUATION OF THERMAL-DIFFUSIVITY FROM STEP-HEATING MEASUREMENTS, International journal of heat and mass transfer, 40(7), 1997, pp. 1647-1655
In this paper the principle and theoretical basis of the step-heating
technique for thermal diffusivity measurement is summarized. Applicati
on of two numerical fitting methods for data reduction-least-squares a
nd Levenberg-Marquardt methods-is described. Results of thermal diffus
ivity estimation from both simulated and experimental data are present
ed and discussed. Copyright (C) 1996 Elsevier Science Ltd.
