Abstract: A bi-dimensional geometrical model was developed and numerically solved considering different cylindrical tungsten specimens, heated to temperatures above 3600 K with current pulses of about (500, 750, and 950) ms duration. A detailed analysis of these virtual experiments indicated large radial temperature differences in all the investigated cases. The range of validity of the long thin rod approximation was verified for various geometries and under different experimental conditions. The developed model may be used to estimate uncertainties due to the use of this approximation and to optimize experimental conditions in real experiments.
