1. Introduction - University of British Columbia

Pulp is dispersed by the shear created in wake turbulence. With the high velocities possible in hydraulic headboxes, high levels of shear can be attained, and therefore good pulp dispersion is possible. However, wake turbulence decays quickly, resulting in pulp re-flocculation. In most paper machines this occurs to a considerable
