 Can a difference in molecular weights cause an eruption in a driven flow of self-organizing immiscible system?R. B. Pandey () and J. F. Gettrust The European Physical Journal B: Condensed Matter and Complex Systems, 2008, vol. 61, issue 1, 83-88 Abstract: Driven flow of a non-equilibrium non-conservative (NENC) system with a mixture of immiscible particles (A,B of molecular weight M A , M B ) exhibits self-organizing patterns (segregation, phase-separation, etc.) in steady-state. The flow response (v) of mass flux density (j) to bias (H), $v=\partial j/\partial H$ in steady-state is found to be sensitive to molecular weight ratio (α=M B /M A ). While the flux density (j) responds linearly to bias for both components (A, B) at α=1, onset of eruptive response occurs at extreme bias (H ↦ 1) at α > 1 where v ↦∞ for heavier (B) and v ↦- ∞ for lighter (A) constituents. Difference in molecular weights (M A , M B ) is not only critical to eruptive flow but also in controlling the flow response prior to this crossover.
