Pomiar gęstości strumienia i współczynnika wnikania ciepła

Three different techniques for determining heat flux and heat transfer coefficient based on temperature measurements inside a solid are presented. Thermal conductivity of the sensor material is temperature dependent. The errors in the determined values of the heat flux and the transfer coefficient are estimated using the variance propagation rule. The third technique based on the Levenberg-Marquardt method has the advantage that can be easily extended to the overdetermined multidimensional inverse heat conduction problems.
