Dynamics of flexible fibers in confined shear flows at finite Reynolds numbers

Abstract: We carry out a numerical study on the dynamics of a single non-Brownianflexible fiber in two-dimensionalCouette flows at finite Reynolds numbers. We employ the bead-spring model of flexible fibers to extend the fluid particle dynamics (FPD) method originally developed for rigid particles in viscous fluids. We implement the extended FPD method using a multiple-relaxation-time (MRT) scheme of the lattice Boltzmann method (LBM). The numerical scheme is validated firstly by a series of benchmark simulations involv… Show more
