Temperature calculation for pulse-heated hot-wire electrodes

The results of a digital simulation for the determination of electrode temperature and near-electrode temperature gradients at a thin wire microelectrode heated by very short heating pulses are presented. The calculation results for temperature and temperature gradients, both as a function of time, are presented and discussed in comparison with experimental results. Fundamental limits and experimentally determined limits of maximum superheating up to temperature values far above boiling point at 1.0125 bar are demonstrated.
