Density-driven instabilities in capillary tubes: Influence of a variable diffusion coefficient
The influence of a variable diffusion coefficient on the gravitational instability at the interface between two variable viscosity fluids in a vertical capillary tube is investigated, based on the three-dimensional Stokes equations. As the viscosity contrast between the fluids grows, the maximum density gradient of the self-similar base concentration profile increases while its location is shif...
متن کاملVariable density and viscosity, miscible displacements in capillary tubes
The displacement of a more viscous fluid by a miscible, less viscous one of lower density in a horizontal capillary tube is studied by means of Stokes flow simulations. Both axisymmetric and three-dimensional simulations are conducted at Péclet numbers up to 104, in order to resolve discrepancies between earlier simulations by [C.Y. Chen, E. Meiburg, Miscible displacements in capillary tubes. P...
متن کاملGravity-driven slug motion in capillary tubes
The velocity of a liquid slug falling in a capillary tube is lower than predicted for Poiseuille flow due to presence of menisci, whose shapes are determined by the complex interplay of capillary, viscous, and gravitational forces. Due to the presence of menisci, a capillary pressure proportional to surface curvature acts on the slug and streamlines are bent close to the interface, resulting in...
متن کاملCoiling instabilities of multilamellar tubes.
Myelin figures are densely packed stacks of coaxial cylindrical bilayers that are unstable to the formation of coils or double helices. These myelin figures appear to have no intrinsic chirality. We show that such cylindrical membrane stacks can develop an instability when they acquire a spontaneous curvature or when the equilibrium distance between membranes is decreased. This instability brea...
متن کاملMechanical instabilities of biological tubes.
We study theoretically the morphologies of biological tubes affected by various pathologies. When epithelial cells grow, the negative tension produced by their division provokes a buckling instability. Several shapes are investigated: varicose, dilated, sinuous, or sausagelike. They are all found in pathologies of tracheal, renal tubes, or arteries. The final shape depends crucially on the mech...
