Data for: A numerical study on the thermal conductivity of H2O/CO2/H2 mixtures in supercritical regions of water for coal supercritical water gasification system

This data article provides the results of the predicted thermal conductivity for H2O/CO2 binary mixtures, H2O/H2 binary mixtures, and H2O/CO2/H2 ternary mixtures via equilibrium molecular dynamics (EMD) simulations and four different theoretical calculation models: (1) KM model for nonpolar gas mixtures; (2) KM model for polar gas mixtures; (3) MS model for nonpolar gas mixtures; (4) MS model for polar gas mixtures. The data presented in this article are related to the article titled " A numerical study on the thermal conductivity of H2O/CO2/H2 mixtures in supercritical regions of water for coal supercritical water gasification system ".
