Immiscible real-coded lattice gas Original Research Article

The real-coded lattice gas method was proposed by Malevanets (1997). In this new lattice gas model, particles have continuous velocity distributions, which would yield to Maxwell–Boltzmann distribution in the equilibrium state. Furthermore, collision and streaming schemes do not depend on the explicit lattice structure. Extension to the three-dimensional calculation becomes straightforward both conceptually and practically. We extended this innovative model to the modeling of immiscible binary fluids by introducing colored particles and their interactions. Benchmark calculations show that Laplace law is satisfied in both 2D and 3D spaces. Simulations of phenomena occurring in the realistic immiscible binary fluids were carried out successfully. The model worked stably, and the qualitative agreement with the well-known droplet behavior has been observed.
