Summary

Flexible wood pulp fibres entangle in a flow field to form larger entities and structures which govern most of the flow characteristics. The flow mechanisms and thus the flow models are vastly different from all other types of non-Newtonian suspension flow. Structured fibre suspensions affect not only pipeline flow, but also mixing, screening, and most pulp and paper processing operations. These unique behaviours are described, practical flow models are presented, and the pipeline design procedures now accepted worldwide are outlined.
