Product Modules: Non-Newtonian, Non-Settling Slurry Flow

• A non-Newtonian fluid is a liquid whose flow properties are not described by a single constant value of viscosity. Examples of non-Newtonian fluids are: polymer solutions, starch suspensions, paint, blood, food products, and mining suspensions of densely packed particles.
• The relation between the shear stress and the strain rate can be either linear or nonlinear. This means that, for fluids exemplifying a nonlinear characteristic, a constant coefficient of viscosity cannot be defined. FluidFlow allows you to describe this relationship of shear-dependent viscosity, according to any of the following rheology models:
• • Bingham Plastic
  • Power Law
  • Herschel-Bulkley
  • Casson

Power law modelling of rheology data

• The example opposite shows viscometer data for a non-Newtonian fitted to a Power Law relationship.
• FluidFlow3 uses different friction factor relationships for each available model, the relationships are valid over all flow regimes.
