Hydrodynamic Fluctuations and Stokes' Law Friction
نویسنده
چکیده
The fri ctional force on a Brownian motion particle can be expressed by means of the time· correlation of the fluctuating force on the particle . We show that this method, applied to a spherical particle in a vi scous incompress ible fluid , leads to Stokes ' Law. The calculation is based on the theory of hydrodynamic flu ctuations due to Landau and Lifs hitz, and on a hydrodynamic theorem due to Faxen.

From local to hydrodynamic friction in Brownian motion: A multiparticle collision dynamics simulation study.
The friction and diffusion coefficients of rigid spherical colloidal particles dissolved in a fluid are determined from velocity and force autocorrelation functions by mesoscale hydrodynamic simulations. Colloids with both slip and no-slip boundary conditions are considered, which are embedded in fluids modeled by multiparticle collision dynamics with and without angular momentum conservation. ...
متن کاملNonlinear dynamics and fluctuations in biological systems (Habilitation thesis)
Inspired by the coordinated beating of the flagellar pair of the green algae Chlamydomonas, we study theoretically a simple, mirror-symmetric swimmer, which propels itself at low Reynoldsnumber by a revolving motion of a pair of spheres. We show that perfect synchronization between thesetwo driven spheres can occur due to the motion of the swimmer and local hydrodynamic friction forces....
متن کاملFlow instabilities of magnetic flux tubes III. Toroidal flux tubes
Context. The stability properties of toroidal magnetic flux tubes are relevant for the storage and emergence of magnetic fields in the convective envelope of cool stars. In addition to buoyancyand magnetic tension-driven instabilities, flux tubes are also susceptible to an instability induced by the hydrodynamic drag force. Aims. Following our investigation of the basic instability mechanism in...
متن کاملImmersed Boundary Method for Boltzmann and Navier- Stokes Solvers with Adaptive Cartesian Mesh
Adaptive Cartesian mesh methods have demonstrated unique abilities for automated mesh generation and dynamic mesh adaptation to flow solution and moving boundaries. However Navier-Stokes (NS) solvers with Cartesian mesh often produce large fluctuations of surface quantities (pressure, skin friction, and heat flux) at solid boundaries. We show that the Immersed Boundary Method (IBM) with adaptiv...
متن کاملIntermittency in two-dimensional Ekman-Navier-Stokes turbulence.
We study the statistics of the vorticity field in two-dimensional Navier-Stokes turbulence with linear Ekman friction. We show that the small-scale vorticity fluctuations are intermittent, as conjectured by Bernard [Europhys. Lett. 50, 333 (2000)] and Nam et al. [Phys. Rev. Lett. 84, 5134 (2000)]. The small-scale statistics of vorticity fluctuations coincide with that of a passive scalar with f...
