Numerical Predictions of Flow-Induced Fiber Orientation in Three-Dimensional Geometries

The effects of coupling the rheology and fiber orientation for a fiber suspension through a orientation-dependent viscosity were also examined. Calculations were performed for axisymmetric contraction flow, axisymmetric expansion flow, and radially diverging flow in a thin cavity. For the axisymmetric contraction and expansion, the flow patterns for the fiber suspension and for the suspending fluid alone were distinctly different. Results from numerical simulation of the contraction were found to quantitatively agree with available experimental data. For the radially diverging flow, the effects of coupling the rheology and fiber orientation were negligible.
