ONE-WAY COUPLING OF FIBER SUSPENSIONS THROUGH A ROTATING CURVED EXPANSION DUCT

Abstract

A numerical method based on the one-way coupling using the Jeffery equation is resented. The influence of the inlet velocity and the initial orientation on the volution of fiber orientation is investigated. It is observed that the rotation mainly ontributes to the pressure rise, and the flow structure is not obviously altered. ue to the one-way coupling, the effects of the inlet velocity and the rotating rate re insignificant.
