Abstract
Abstract
Surface tension is one of the important properties in enhanced
oil recovery, particularly for gas-liquid displacement in porous
media and separation process. It acts to keep interfaces of two
immiscible fluids smooth, where two or more curved
interfaces create pressure differences. The estimation and
measurement of surface tension currently are made by
capillary rise such as the ring method and the pendant drop
method. In this paper, the lattice-gas automata method is being
explored to be used in estimating the surface tension between
two immiscible fluids in a porous medium. The main idea of
immiscible lattice-gas model in this paper was the introduction
of two species of particles (red for gas and blue for oil) to
represent two immiscible fluids. The great advantage of the
model was that interfaces and the interfacial dynamics were
generated spontaneously. The surface tension was estimated
by the Laplace’s equation and ranged between 0.00585 -
0.00603. In general, simulation results are in good quantitative
estimation and this simulation also allow us to model liquidliquid
or gas-liquid interactions. The aim was to see the
suitability of lattice-gas automata in representing two
immiscible fluids of oil and gas.
