The Immersed Boundary Method for incompressible fluid–structure interaction

In this paper the Immersed Boundary Method is presented, with some recent developments. The method is used to analyze fluid–structure interaction problems. Different aspects of the method are illustrated by applying it to blood flow in the heart and a flapping filament (flag-in-wind) problem.

Numerical Studies of Viscous Incompressible Flow between Two Rotating Concentric Spheres

The problem of determining the induced steady axially symmetric motion of an incompressible viscous fluid confined between two concentric spheres, with the outer sphere rotating with constant angular velocity and the inner sphere fixed, is numerically investigated for large Reynolds number. The governing Navier-Stokes equations expressed in terms of a stream function-vorticity formulation are r...

Interaction between two Fuzzy Spheres

We have calculated interactions between two fuzzy spheres in 3 dimension. It depends on the distance r between the spheres and the radii ρ1, ρ2. There is no force between the spheres when they are far from each other (long distance case). We have also studied the interaction for r = 0 case. We find that an attractive force exists between two fuzzy sphere surfaces.

Hydrodynamic instability of a thin viscous film between two drops.

Linear stability analysis is employed to derive analytical expressions for the growth rate of disturbances applied to a thin plane-parallel film trapped between two drops. From these expressions, the band of unstable wavenumbers and the "most dangerous" wavenumber are identified for systems in the absence and presence of insoluble surfactant. Marangoni effects are shown to exert a stabilizing i...

Hydrodynamic Interaction of Rough Spheres

Abstract The approach of two spheres along their line of centres is analyzed assuming that each sphere is covered by a porous layer. The slip of the fluid at the surface of the porous layers then permits the spheres to touch without a singularity in the associated force. In a corresponding analysis for flat surfaces, an analytical formula for the force is obtained. This force is also finite for...
