Description
Summary:Pseudopotential lattice Boltzmann models have emerged as successful methods to simulate liquid‐vapor coexistence systems. However, the equation of state (EOS) of such systems, which is found to be thermodynamically consistent, is unique and lacks the potential to cover a broad range of physical fluids. In this study, we employ multiple pseudopotentials and extend the consistent EOS to enhance the capability of pseudopotential models in reproducing a wider range of thermodynamic states. The new system has the format which preserves the consistency between the lattice pressure tensor and the free energy density. (© 2014 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
