Applying of dynamic filtering method to simultaneous determination of the thermal conductivity and dyfussivity of the solids

The combined theoretical and experimental method for simultaneous determination of thermal properties (thermal conductivity λ and dyfussivity a) of different solid bodies has been presented in this paper. The mathematical model of the considered problem has been formulated. Using the control volume method the equations of the model have been transformed to a nonlinear discreet form of stand equation demanded by dynamic filtering method. In order to determine the thermal conductivity and dyfussivity of investigated material the inverse heat conduction coefficient problem has been solved by applying dynamic filtering method. Using test stand the some data to solving inverse heat conduction problem has been determined. The preliminary results of investigation has been presented. The results received by applying the present method have been compared with date from literature.
