Comparison of Methods for Determining the Thermal Conductivity in Induction Heated Industrial Rotating Calenders

In many technical applications it is necessary to know thermal diffusity and heat conduction in solids, liquids and gaseous. In case of solid bodies the experimental determination of those properties requires use of special laboratory stands which provides the appropriate initial and boundary conditions necessary to solve invert problems. In the paper two methods of determine thermal property of metals has been presented and discussed. First method is based on classical optimization methods and the second one by artificial neural network, which is trained with data from numerical model of investigated body. Both method were tested on real laboratory model.
