Dynamics of flexible fibers in shear flow.
Dynamics of flexible non-Brownian fibers in shear flow at low-Reynolds-number are analyzed numerically for a wide range of the ratios A of the fiber bending force to the viscous drag force. Initially, the fibers are aligned with the flow, and later they move in the plane perpendicular to the flow vorticity. A surprisingly rich spectrum of different modes is observed when the value of A is syste...
متن کاملSimulation of Flexible Fibers in Stokes Flow
When elastic fibers are immersed in a Newtonian fluid, the behavior of the system, or the “fiber suspension” becomes non-Newtonian. Understanding the dynamics of such systems is of particular interest in a wide variety of fields, including locomotion of microorganisms, paper and pulp industry, microfluidics etc. When these fibers are immersed in the fluid at low Reynolds number, the elastic equ...
متن کاملApproach to the nonequilibrium time-periodic state in a steady shear flow model
The standard nonequilibrium molecular dynamics algorithm for steady shear flow (SLLOD ) employs Lees–Edwards periodic boundary conditions. It is not widely known that these boundary conditions make the system non–autonomous. The "steady state" shear stress is in fact time periodic. The standard response theory derivations for steady shear do not take proper account of these non–autonomous terms...
متن کاملCharacteristic periodic motion of polymers in shear flow.
The motion of both free and tethered polymer molecules as well as rigid Brownian rods in unbound shear flow is found to be characterized by a clear periodicity or tumbling frequency. Periodicity is shown using a combination of single molecule DNA experiments and computer simulations. In all cases, we develop scaling laws for this behavior and demonstrate that the frequency of characteristic per...
متن کاملTransport of flexible chiral objects in a uniform shear flow
The transport of slightly deformable chiral objects in a uniform shear flow is investigated. Depending on the equilibrium configuration one finds up to four different asymptotic states that can be distinguished by lateral drift velocity of their center of mass, rotational motion about the center of mass and deformations of the object. These deformations influence the magnitudes of the principal...
