Modelling of the thermal field of hot electrode and the controlled sample at thermoelectric testing of metals

Abstract

The article presents the results of simulation of the temperatures of hot electrode and controlled sample during measuring the thermoelectric performance of metals and alloys. The temperature dynamics in the contact zone with the planar and point contacts between the hot electrode and the controlled sample is presented in the paper. The influence of the temperature dynamics on thermo electromotive force is shown. Simulation was carried out for two hot electrodes made of copper and aluminum. Controlled sample was made of steel ST3 (analogue of A57036).
