Modelling of the flow in the distribution plate of a spin pack
A Computational Fluid Dynamics analysis of the flow through the distributionplate of a fibre spinning pack has been performed. The features of the flow that are relevant to polymer processing are addressed, such as the wall shear rate, residence time and dead zones. An analyticalmodel, that agrees very well with the calculations, is proposed. It also yields insight into the role played in the flow by different design parameters of the distribution plate. This model, primarily based upon a Newtonian fluid, is also extended to a shear thinning one.
