  • Tackling Difficult Mixing Problems AIChE

    Mixing non-Newtonian fluids may be doubly complicated when the mixing process creates the non-Newtonian proper-ties. For example, a formulation process may start with a low-viscosity liquid, and mixing causes the viscosity to increase until the fluid becomes non-Newtonian. Sometimes mixer power may be used as an indicator of final fluid viscosity.
