Abstract
In this paper we apply a finite difference lattice Boltzmann model to study the phase separation in a
two-dimensional liquid-vapor system. Spurious numerical effects in macroscopic equations are discussed and
an appropriate numerical scheme involving flux limiter techniques is proposed to minimize them and guarantee
a better numerical stability at very low viscosity. The phase separation kinetics is investigated and we find
evidence of two different growth regimes depending on the value of the fluid viscosity as well as on the
liquid-vapor ratio.
