Flow structure and loads over inclined cylindrical rodlike particles and fibers
Mohammed Kharrouba, Jean-Lou Pierson, Jacques Magnaudet
Abstract
We use fully-resolved simulations to predict the force and torque acting on a long cylinder or a fiber inclined with respect to the incoming flow. Results obtained in the viscous regime are compared with predictions of the slender-body theory, possibly incorporating finite-inertia corrections. Numerical results are used to build approximate models for the force and torque valid from creeping-flow conditions up to the upper limit of the stationary inertial regime.
