Blister Ring Mixers

The shear stress that the material experiences for flow across a blister mixer can be estimated using Eqs. 8.12 and 8.13. For this calculation, the flow in the axial direction is ignored to simplify the mathematics, and thus only the angular flow is considered. Ignoring the axial flow causes the calculated shear rate to be lower than in the actual channel. [Pg.360]
