Dynamic Behavior of Elliptical Particles in a Pressure Driven Flow, 2000 Engineering Conference Proceedings

Dewei Qi, Raja Aravamuthan--Dynamic behavior of ellipticalsingle and multi-particles in a pressure driven flow is investigated using a lattice Boltzmann simulation method. It is found that a neutrally buoyant particle migrates to an equilibrium position between the wall and the channel center and the elliptical particle has a larger probability to be oriented in the flow direction than in the cross flow direction. The results suggest that a component of shear forces in the cross flow direction should be created in the jet of headbox to increase the orientation of fibers in the cross flow direction.
