High Reynolds number oscillating contact lines
For the eventual use as regards wave generation and damping, we investigate oscillating contact lines on vertical walls. Stainless steel is used rather than the glass of Ting and Perlin [J. Fluid Mech. 295 (1995) 263] for the vertically sinusoidally oscillating plate over a large range of Reynolds numbers. The non-wetting stainless steel minimizes the static meniscus ignored in our analysis. Ot...
متن کاملStochastic low Reynolds number swimmers.
As technological advances allow us to fabricate smaller autonomous self-propelled devices, it is clear that at some point directed propulsion could not come from pre-specified deterministic periodic deformation of the swimmer's body and we need to develop strategies for extracting a net directed motion from a series of random transitions in the conformation space of the swimmer. We present a th...
متن کاملMany-body effects and matrix inversion in low-Reynolds-number hydrodynamics
It is shown that the method of reflections in resistance form ~with truncated multipoles! is one of many possible iterative methods to obtain the inverse of the mobility matrix ~with the same truncation! in low-Reynolds-number hydrodynamics. Although the method of reflections in the mobility form is guaranteed to converge, it is found that in the resistance form the method may fail to converge....
متن کاملLow-Reynolds-number swimming at pycnoclines.
Microorganisms play pivotal functions in the trophic dynamics and biogeochemistry of aquatic ecosystems. Their concentrations and activities often peak at localized hotspots, an important example of which are pycnoclines, where water density increases sharply with depth due to gradients in temperature or salinity. At pycnoclines organisms are exposed to different environmental conditions compar...
متن کاملQuiet swimming at low Reynolds number.
The stresslet provides a simple model of the flow created by a small, freely swimming and neutrally buoyant aquatic organism and shows that the far field fluid disturbance created by such an organism in general decays as one over distance squared. Here we discuss a quieter swimming mode that eliminates the stresslet component of the flow and leads to a faster spatial decay of the fluid disturba...
