Flow characteristics such as velocity and pressure drop have a dependence on fluid properties. Slurry systems with settling solids and non-settling slurry systems both require special consideration to accurately model system operation as the viscosity becomes non-Newtonian. In the case of settling solids, the local velocity is critical as this must be above the threshold set by the slurry’s deposition velocity. Non-settling slurries can be modeled with Power Law, Bingham Plastic or Homogeneous Scale-Up correlations and will thus behave differently than common Newtonian fluids. Non-settling, non-Newtonian fluid modeling is part of the standard AFT Fathom and (for waterhammer) packages. AFT Fathom and AFT Impulse can model settling solid systems with the Settling Slurry add-on module, and the standard software packages are equipped to handle non-settling applications.
