Turbulent Shear and Breakup of Flocculated Biomaterial in Centrifuge Inlets
Analyses and simulations of a lab‐scale device for determining floc strength are presented together with simulations of two different hermetic disc‐stack centrifuge inlets. Two methods for determining the turbulent shear stresses on flocs in hermetic centrifuge inlets are described. A model for the...

| Sumario: | Analyses and simulations of a lab‐scale device for determining floc strength are presented together with simulations of two different hermetic disc‐stack centrifuge inlets. Two methods for determining the turbulent shear stresses on flocs in hermetic centrifuge inlets are described. A model for the average shear rate in a hermetic centrifuge inlet is proposed. A correlation for estimating the floc size of the centrifuge feed after passing the high‐shear zone of the inlet is derived. |
