A Semiempirical Evaluation of the Thermal Conductivity in Ablated Dense Tungsten Plasma

For understanding the properties of ablated dense tungsten, we have proposed a semiempirical evaluation of thermal conductivity based on the Wiedemann–Franz law. The electrical conductivity of ablated dense tungsten has been evaluated by the exploding-wire discharges in water and the isochoric heating of wire in a vacuum. The results indicate that the thermal conductivity derived from the electrical conductivity ranges from 0.1 to 100
