Lattice Boltzmann Simulation of Nucleation

In this paper, we propose a lattice Boltzmann model for two-phase flows pertinent to thermal nonideal fluids. The LBM introduces a fictitious forcing term and recovers thermohydrodynamic equations for nonideal fluid through the Chapman-Enskog expansion procedure. The latent heat is identified by a comparison of density with enthalpy in the simulation of the bubble generation. The numerical measurements of departure radius of bubbles for surface tensions and for contact angles approximately agree with experimental equation. Simulations of pool boiling with heat transfer are carried out, showing the applicably of the model for two-phase flows with thermal effects. Using finite difference Lattice Boltzmann method ensures numerical stability of the schem
