Direct observation of hydrodynamic rotation-translation coupling between two colloidal spheres.
By combining optical tweezers with polarization microscopy, the hydrodynamic coupling between position and orientation fluctuations in a pair of colloidal spheres has been measured. Imaging of birefringent particles under crossed polarizers allows for the simultaneous determination of the positions and orientations of both particles. The temporal cross-correlation function between random displa...
متن کاملHydrodynamic coupling of two brownian spheres to a planar surface.
We describe direct imaging measurements of the collective and relative diffusion of two colloidal spheres near a flat plate. The bounding surface modifies the spheres' dynamics, even at separations of tens of radii. This behavior is captured by a stokeslet analysis of fluid flow driven by the spheres' and wall's no-slip boundary conditions. In particular, this analysis reveals surprising asymme...
متن کاملHydrodynamic 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.
متن کاملMeasurement of the hydrodynamic corrections to the Brownian motion of two colloidal spheres
The hydrodynamic coupling between two isolated 0.97 mm diameter polystyrene spheres is measured by reconstructing their Brownian motion using digital video microscopy. Blinking optical tweezers are used to facilitate data collection by positioning the spheres in the microscope’s focal plane and in close proximity to one another. The observed separation dependence of the spheres’ relative and ce...
متن کاملCoupling between two inlets: Observation and modeling
[1] The resonance coupling between two adjacent inlets is investigated. Field evidence of this natural phenomenon is found for two elongated inlets in the region of Ciutadella, Menorca Island, in the Western Mediterranean (Ciutadella and Platja Gran). To illustrate the fundamental features of the problem, analytical solutions for two rectangular inlets with constant depth are constructed and an...
