Abstract
We present here a technique to compute electronic thermal conductivity of fluids using quantum-molecular dynamics and the formulation of Chester-Tellung for the Kubo-Greenwood formula. In order to validate our implementation, the electrical and thermal conductivities of liquid aluminum were determined from above the melting point up to . Results agree well with experimental data for Al at . The Lorentz number, defined as , where is the thermal conductivity, is the electrical conductivity, and is the temperature, is close to the ideal value of for metals, and the Wiedemann-Franz law is verified.
