Temperature distribution near thermocouples within fuel rod imitators with electric heating

In heat transfer studies surfaces with the direct electrical heating are often employed. In this case using thermocouples for the temperature control results in the electric and temperature field distortions. The error due to thermocouple presense has been measured by means of thermovision. The experiments have shown the value of this error to be comparable with that due to thermal conductivity losses through the electric conductors of the thermocouple. The results of theoretical calculations ogree with the experiment
