Sažetak
In order to design and construct the didactic experimental device for measuring the thermal conductivity of metals, first the numerical modelling approach was applied. The numerical modelling was performed by implementing both the finite element method for transient heat flow and Python programming language. The conceptual design of device was confirmed based on the numerical results of thermal conductivity for three different metals (carbon steel, copper and aluminium). The didactic experimental device was constructed and tested by measuring the thermal conductivity of test specimens made of carbon steel, copper and aluminium. The experimental device proved to be easy to use and practical for educational purposes. The analysis of experimental results, together with the comparison of numerical and experimental results, have showed that the numerical model generally overestimates the rate of change of thermal conductivity. Finally, the reliability of experimental device still has to be confirmed by testing the certified material with known thermal conductivity.
