The design of mixers, impellers, and separators involves several engineering challenges. For mixers and impellers, the selection of the right type is crucial as they physically do the mixing1. The unique shear and fluid flow patterns of impellers result in the desired mix. Managing non-Newtonian viscosity is a challenge as it can lead to inadequate fluid motion and unmixed portions in a tank. For separators, the computational method is used to investigate the flow field, power consumption, pumping capacity, hydraulic efficiency, and mixing time.

Particleworks creates digital prototypes of mixers, separators and extruders to investigate:

  • Impeller and screw design improvements
  • Power requirements for a given operating conditions
  • Non-Newtonian fluid mixing
  • Multiphase mixing (also with granular materials)
  • Shear stresses in the fluid phase and shear heating
Mixing simulations with Particleworks analyzing highly viscous materials (non-Newtonian) as well as solid powders. The mesh-less approach enables to test several impeller designs in one day, while visualizing dispersion and mixing index.


By enabling shear and temperature dependent viscosity with several pre-existing models, Particleworks allows simulations of carbon fiber injection of resin or e-motor potting and coating.
Extrusion simulation with Granuleworks (solid particles) giving insights about resistive torque.
Thanks to an advanced viscosity solver, Particleworks allows for adhesive deposition testing with simulation.
