• 論文の詳細を見る

• We investigate effect of external flow on domains in two-dimensional phase-separating binary fluid. By use of the coupled Cahn-Hillard and Navier-Stokes equations, we study stability of a lamellar domain under two-dimensional Poiseuille flow within a linear stability analysis. We derive stability eigenvalues for long wavelength fluctuations. The two-dimensional Poiseuille flow has the effect of mixing a stable zigzag mode and an unstable varicose mode so that they both become stable. The width of the stable lamellar domain depends on a distance from wall.
