Papermaking flows are extremely challenging for modelling and simulation, if one accepts their full complexity. A wide range of particles, including fibres, fibre fragments (fines) and fillers (non-organic particles), flow and interact with each other in a non-dilute suspension, a complex geometry and at a high flow rate. Different simulation approaches are reviewed from particle-level simulations, through meso-scale simulations to the full flow geometry of the papermaking line. Their application to papermaking and potential to provide fundamental understanding as well as direct process-optimization support are discussed.

“…To avoid this problem, we consider a one-dimensional contracting channel flow in the x-direction, and constrain the orientation of the fibres to the plane φ = π/2, so that = (x, θ). In this case the rotation of the fibre can be described by [54,55] …”

Abstract. An orientation distribution function is applied to describe the orientation distribution of polymer-fibers composites in shear-ellipsoidal extensional flow. And a mathematical model is established to simulate orientation distribution in this flow. Furthermore, the analytical solutions of differential equations on plant fibers orientation can be acquired in complex flow field. Therefore, analytical solution of differential equation on plant fiber orientation distribution is obtained.
