The above "copper.zip" folder contains electrical conductivity over 6 kK, 10 kK, 20 kK, and 30 kK isotherms (first column: density, second column: electrical conductivity), as well as a complete tabulated dataset from 1 - 50 kK, and 0.001 - 8.94 g/cm3 (first column: density, second column: temperature, third column: electrical conductivity).
All units are SI (kg/m^3, K, S/m)
Using a theoretical platform, a semi-empirical conductivity dataset for copper was generated. In the high density regime, a modified form of the Knoepfel conductivity is used. At lower densities, an ionization potential corrected Saha equation is used to determine the degree of ionization, which when coupled with a semi-empirical hard-sphere model allows for the calculation of electrical conductivity. The results have been shown to be accurate with the experimental conductivity data of DeSilva and Katsouros [A.W. DeSilva, J.D. Katsouros, Phys. Rev. E, 57, 5945 (1998)]. Additionally, the model demonstrated predictive capabilities via MHD simulation of an exploding wire. In its present state, the model has demonstrated practical accuracy from room temperature and density to 30 kK, and densities as low as 0.01 g/cm3, making the model ideal for the simulation of electrically exploded metals.
