Abstract

An interacting lattice gas model is used to study flow of immiscible components A and B (molecular weights MA and MB,MAjB except at the extreme bias H→1 where jA→jB. Flow response becomes complex if the constituents from their source are released according to their current lattice concentrations (an interacting source): a crossover occurs from jA>jB at low bias (H≤0.4) to jB>jA at higher bias (H>0.4). Constituent with the lower molecular weight (A) responds linearly on increasing the bias except at very high bias (H≥0.8) 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→1.
