Abstract:

An interacting lattice gas model is used to study flow of immiscible components A and B by Monte Carlo simulations. Concentration gradients and hydrostatic pressure bias drive these constituents from their source at the bottom against gravitational sedimentation in an effective medium. Response of their flux densities to the hydrostatic bias H are examined. If both constituents are released with equal probabilities a non-interacting source, their flux densities respond linearly to bias except at the extreme bias. Flow response becomes complex if the constituents from their source are released according to their current lattice concentrations. Constituent with the lower molecular weight A responds linearly on increasing the bias except at very high bias where the response becomes negative. The heavier component B responds non-linearly a high response at low values of H is followed by a linear response before the onset of eruptive response at high range of H. The volatility parameter diverges as eruption occurs at H yields 1.
