    A thin “rope” of viscous fluid falls from a sufficient height of coils as it approaches a rigid surface. Here we perform a linear stability analysis of steady coiling, with particular attention to the “inertio-gravitational” regime in which multiple states with different...

    An asymptotic solution of the Enskog equation is obtained by an expansion in two parameters: ε, estimating the deviation from equilibrium and ε, the Knudsen number. It is shown that different relations between these parameters imply that the different versions of approximate hydrodynamic...

    We study the effect of adsorbed surfactant on drop deformation in linear flows by means of analytical solutions for small perturbations of the drop shape and surfactant distribution, and by numerical simulations for large distortions. We consider a drop with the same viscosity as the suspending...
