This work was started by Gian Carlo Bussolino when working at the IPCF (Istituto Processi Chimico-Fisici – CNR), with Giuseppe Annino and Carlo Ferrari (now at the INO), in collaboration with Francesco Righini from the Istituto Nazionale di Ricerca Metrologica (INRIM) in Torino (Turin).
It is a very specialized paper that demonstrates how to use a simulation software via a finite element method to evaluate the uncertainty of experimental results obtained with high precision levels. The experimental results are related to the former work of Gian Carlo Bussolino with Francesco Righini, when both were part of the Thermophysical Property Research Group of the Istituto Metrologia “G. Colonnetti” (IMGC – CNR), now INRIM (Istituto Nazionale Ricerca Metrologica). Pulse experiments are performed on electrical conductors taking the specimens from room temperature to their melting point (3690 K for tungsten) in less than 1 s with a current pulse. During the experiment various quantities are measured with micro-to-millisecond time resolution, computing then with high precision several thermophyisical properties (heat capacity, enthalpy, electrical resistivity, hemispherical total emissivity,…).
In more general terms this paper demonstrates the possibility of virtual pulse experiments in which the model replicates well the real experiment and modeling results very close to reality can be used to optimize the parameters of the real experiment. Gian Carlo Bussolino has acquired competence in this simulation tool that might also be used in other INO activities.
