Hydrodynamic coupling of two sharp-edged beams vibrating in a viscous fluid

Hydrodynamic coupling of two sharp-edged beams vibrating in a viscous fluid.

In this paper, we study flexural vibrations of two thin beams that are coupled through an otherwise quiescent viscous fluid. While most of the research has focused on isolated beams immersed in placid fluids, inertial and viscous hydrodynamic coupling is ubiquitous across a multitude of engineering and natural systems comprising arrays of flexible structures. In these cases, the distributed hyd...

Hydrodynamic coupling between micromechanical beams oscillating in viscous fluids

We analyze the hydrodynamic coupling between long, slender micromechanical beams !microbeams" deployed in an array and oscillating in a viscous, incompressible fluid. The unsteady Stokes equations are solved using a boundary integral technique in a two-dimensional plane containing the microbeam cross sections. The oscillations of nearest neighbor and the next neighbor microbeams couple hydrodyn...

Hydrodynamic Loading of Microcantilevers Vibrating in Viscous Fluids

Hydrodynamic coupling between two fluid membranes.

The coupled in-plane diffusion dynamics between point-particles embedded in stacked fluid membranes is investigated. We calculate the contributions to the coupling longitudinal and transverse diffusion coefficients due to particle motion within the different as well as the same membranes. The stacked geometry leads to a hydrodynamic coupling between the two membranes.

Numerical simulation of flow hydrodynamic around dolphin body in viscous fluid

The biomimetic and hydrodynamic study of aquatic animals is one of the most challenging computational fluid dynamics topics in recent studies due to the complexity of body geometry and the type of flow field. The movement of the aquatic body, and particularly the tail section and the corresponding movement of fluid around the body, causes an unsteady flow and requires a comprehensive study of t...
