Two-fluid model based on the lattice Boltzmann equation.
A two-fluid model for dispersed two-phase flows based on the lattice Boltzmann equation (LBE) is proposed. Two sets of LBEs are used to describe the two phases. The continuity and Navier-Stokes equations for the continuum-based two-fluid model are obtained from the LBEs by adding a pressure term. The phase hold-up is readily calculated from the partial pressure of each phase because the two phases are described by the ideal gas equation of state. A simulated laminar gas-liquid two-phase flow gave good agreement with the results calculated by the conventional continuum-based two-fluid model.
