Abstract

A liquid-gas model of lattice-gas is made by adding long-range interaction to lattice-gas and can simulate phase separation similar to that in the van der Waals' liquid-gas theory. This liquid-gas model can generate a circular dense-phase in the rare phase. In this paper, the deformation of the circular dense-phase by external force is simulated using the two types of liquid-gas models of lattice-gas, which are distinguished by the type of long-range interaction. It is observed that one type of model shows the valid deformation and the other shows the unphysical deformation. It is found by numerical experiments that this difference of the deformation is caused by dynamical pressure anisotropy of the liquid-gas model of lattice-gas.
