We present a model to describe the thermodynamic and transport properties of dense plasmas. The electronic and ionic structures are determined self‐consistently using finite temperature density functional theory and the Gibbs‐Bogolyubov inequality. The main thermodynamic quantities, i.e., internal energy, pressure, entropy, and sound speed are obtained by numerical differentiation of the plasma total Helmholtz free energy. Electronic electrical and thermal conductivities are calculated from the Ziman approach. Ionic transport coefficients are estimated using those of a hard‐sphere system and the Rosenfeld semi‐empirical “universal” correspondence between excess entropy and dimensionless transport coefficients of dense fluids. Numerical results and comparisons with quantum molecular dynamics calculations and experiments are presented and discussed.
